00:00From super-fast trains to industrial mining cranes, these machines use powerful magnets to get the job done.
00:07Join me as we take a look at 15 of the most amazing machines that use magnets.
00:14Number 15. Maglev train transportation.
00:17Maglev, which comes from the phrase magnetic levitation, is a system of train
00:22transportation that uses one set of magnets to repel and push the train up off the track and another set to move the elevated train
00:29ahead. This maglev technology controls the train's stability and speed, and as the propulsion and levitation requires no moving parts,
00:36these trains can often be quieter and smoother than conventional trains, not to mention having the ability to accelerate and decelerate much faster.
00:44As such, maglev trains have the potential for much higher speeds than their more conventional
00:49counterparts, and have even set several speed records. The Shanghai maglev train, for instance,
00:54also known as the Shanghai TransRapid, has a top speed of
00:58430 kilometers an hour, covering a distance of 30 kilometers in 8 minutes,
01:03making it the fastest operational high-speed maglev train.
01:07Unfortunately, however, the safety and comfort of the passengers is far down on the list of maglev train priorities,
01:13and running costs can be four to five times more expensive than standard trains,
01:17which is probably why they're only currently operational in South Korea, China, and Japan.
01:23Number 14. Automotive assembly lines.
01:27Without magnets, the automotive industry would hear its metaphorical tires come to a screeching halt.
01:33Magnets are used extensively in the automotive industry, from the production line right through to the final product. During production,
01:40for example, parts must be held in place,
01:42so the machines on automotive assembly lines use huge magnets to lift large components onto the car-to-be.
01:48Outer shells, doors, various mechanical components, all of these parts need to be put together
01:53precisely and be held firmly in place while that's occurring.
01:57But those various parts also contain a wide array of magnets themselves.
02:01You know that annoying beeping sound you get when you forget to fasten your seat belt?
02:05Well, that's all down to something called a reed switch, which changes the flow of electricity in the presence of a magnet.
02:11It's the same with your car doors being open.
02:13They too operate on a reed switch system, where the alarm sounds depending on whether the switch is in contact with the magnet inside the door.
02:21Magnets are used in ABS systems to help attach them to the car and keep them in place.
02:25And then we've got car roof magnets.
02:27You know the way the taxi signs or domino pizza signs hang to the car roof as if by magic?
02:32Yep, magnets. And did I mention the neodymium magnets used in car tracking systems?
02:37So there you go. Magnets in the machines on the production line. Magnets in the parts themselves.
02:42Magnets to hold parts to other parts. Magnets, magnets everywhere.
02:46Number 13. Wendelstein 7X Stellarator.
02:51The Wendelstein 7X Stellarator is an experimental nuclear fusion reactor.
02:56And like all upcoming nuclear fusion reactors, its goal is to replicate the processes at play within the sun.
03:02This is done by exposing streams of plasma to extreme temperature and pressure, thereby forcing atoms to collide,
03:09which then fuse together to produce incredible amounts of energy.
03:12Easy, huh?
03:13Well, how do we achieve that? Well, by magnets, of course.
03:16The technical core of the Wendelstein 7X consists of 50 superconducting magnet coils.
03:22And if you're not aware of the powerful effects of this kind of magnet field can have,
03:26then you might want to consider that this incredible machine has produced plasma, which is twice as hot as the sun itself.
03:32Built in Greifswald, Germany by the Max Planck Institute for Plasma Physics and completed in October 2015,
03:39the Wendelstein 7X is designed to bring the dream of clean, limitless energy closer to reality.
03:45And it's currently the world's largest fusion device of the Stellarator type.
03:49Number 12. Agricultural Machinery.
03:53Magnets are used in a wide variety of agricultural machinery, such as TMR mixers, feed grinders, roller mills, hammer mills, feed wagons,
04:02and not to mention the weirdly named cow magnets.
04:05And no, by the way, this isn't a way to pick up cows and move them from field to field.
04:09But with that said, they're very important when it comes to their health and well-being,
04:13as they're designed to remove iron particles and keep sharp objects out of the cow's feed.
04:18On that note, a piece of agricultural machinery that provides a similar purpose is the magnetic de-stoner.
04:24But what does it do? Well, let's take grain production as an example.
04:28Before processing, grain can contain all types of impurities, stone, metal, glass, mud balls, black stones, rat feces.
04:35And the magnetic de-stoner is designed to produce an intense magnetic field,
04:39which throws the impurities out and provides clean, raw grain,
04:43which isn't likely to result in anyone coming down with a terrible disease or ruptured internal organs,
04:49simply after eating their morning cereal.
04:52Number 11. Wind Turbines.
04:56We've all seen wind turbines dotting the landscape,
04:59and most of us probably assume that the trick to making these things go round is clearly explained in the name.
05:04In other words, it's all down to the wind.
05:06Well, yes. Okay, I'd never try to convince you that wind isn't the main ingredient for any good wind turbine,
05:13but magnets are also a major part of what makes them work the way they do.
05:17You see, in every wind turbine and generator, you'll find one or more incredibly strong permanent magnets,
05:23and possibly even permanent magnet generator systems, or PMGs, which eliminate the need for gearboxes.
05:29This means that instead of needing electricity to emit a magnetic field,
05:32large neodymium magnets can be used to produce their own,
05:36eliminating the need for parts used in previous generators,
05:39while decreasing the wind speed required to produce energy.
05:42And as wind turbines are all about producing sustainable, clean energy, all of these things are an added bonus.
05:49Number 10. Magnetic Brakes on Roller Coasters.
05:52We all love roller coasters, right?
05:54The way you're thrown upside down at high speeds, screaming out of either terror or exhilaration.
05:59But either way, you'll know it'll all be over quickly, and soon enough, you'll come to a standstill.
06:04And that's all because of magnetic brakes.
06:06You see, rather than slowing the train down via friction, which isn't always reliable due to rain and other natural occurrences,
06:12magnetic brakes never come into contact with the roller coaster and rely on magnetic properties and resistance.
06:19Consisting of one or two rows of neodymium magnets,
06:22magnetic brakes can come into effect when a metal fin passes between the rows of magnets,
06:27generating eddy currents, which then create a magnetic force opposing the fin's motion.
06:32The braking force which happens is directly proportional to the speed at which the fin is moving through the brake element,
06:38which means that braking power is gradually increased,
06:41so that the people on the ride don't experience rapid changes in deceleration
06:45and have their wigs, jewelry, and dentures flying into other carriages once they stop.
06:49Despite all the positive aspects of magnetic brakes,
06:52the disadvantage is that they can't completely stop a train,
06:55and so can't be used like traditional block brakes, requiring another set of brakes to hold a train in place.
07:01But hey, that doesn't make the fact that your roller coaster is being stopped by magnets any less cool.
07:05Well, or terrifying.
07:08Number 9. AMS, International Space Station
07:13The AMS, or Alpha Magnetic Spectrometer,
07:16is a particle physics experiment module mounted on the International Space Station,
07:20which is used to detect and measure antimatter in cosmic rays.
07:24The experiment is run by CERN, who are obviously responsible for the Large Hadron Collider,
07:29and therefore know a thing or two about particle physics,
07:32and the principal investigator is Nobel laureate physicist Samuel Ting.
07:36So this is one serious experiment.
07:38At the heart of this incredible piece of machinery is something called the Permanent Magnet,
07:43which also flew on the Space Shuttle Discovery in the early version of this experiment.
07:47And without this, particles would fly directly through the detectors in a straight line,
07:51leaving no trace of themselves or their charge behind.
07:55The Permanent Magnet is a 1.1 meter by 0.8 meter cylinder.
07:59It's made up of more than 6,000 2x2 by 1 inch blocks of neodymium iron boron magnets,
08:05which create a magnetic field 3,000 times stronger than that of the Earth.
08:09In fact, it's so strong that if it was used in the wrong way,
08:12it could draw astronauts to it during spacewalks,
08:16or even change the orientation of the space station itself.
08:25Industrial magnets are used in a wide variety of machines and equipment right across the mining industry,
08:30not least of which is the huge magnetic drills used at the very heart of the mining process.
08:35But perhaps one of the most important and unsung uses is to remove unwanted metal from the production line,
08:41which has been left behind due to excavation, explosives, or human error.
08:45These pieces of metal, known as tramp metal, can easily tear conveyor belts
08:50and cause damage to vital mining equipment, such as pulverizers and crushers.
08:55Magnets used at the beginning of the conveyor system extract larger metal scraps,
08:59such as bucket teeth, bolts, and even tool bits,
09:02while magnets later in the production line can remove smaller ferrous impurities.
09:06This is done by using a variety of magnets, including suspended plate magnets and cross-belt separators,
09:12which are extremely powerful and hung above the conveyor belt system,
09:15and able to extract tramp metal from fast-moving belts with deep burden depths.
09:20Magnetic drum separators are also used, which pull tramp metal particles to the outer drum
09:25and then direct it away from the output line.
09:27There's no doubt that without magnets, the mining industry would look a whole lot different.
09:36Our next entry is a simple device, but one that's incredibly important to the art of welding.
09:41And without welding, the industrial world would most likely grind to a standstill.
09:46Welding magnets usually contain alnico, neodymium, or samarium cobalt,
09:51which means that they have an extremely strong magnetic field
09:54and can stick to all metal surfaces to ensure a quick setup and accurate hold.
09:58As such, these welders can work hands-free, making the overall process a lot safer and significantly more secure.
10:05There are several different types of welding magnets, including welding magnets with switches,
10:09which allows you to turn the magnetism on or off.
10:12Multi-angle welding magnets, which as the name would suggest,
10:15allows you to hold the work at 45, 90, and 135 degree angles.
10:19Arrow welding magnets, which are shaped like an arrow
10:22and can be used as a double-sided holder for welding and assembling.
10:26And adjustable welding magnets, which are capable of swiveling around a full 360 degrees
10:31and can hold the metal at any angle.
10:33It's simple, but extremely effective.
10:366. Guitar Pickups
10:38Without our next little device, we would have missed out on 70 years of contemporary music,
10:43which is an impressive boast for such an unassuming gadget.
10:46That's right, without the guitar pickup, there would have been no electric guitar,
10:50because this is very much the thing that made the electric guitar,
10:53and therefore rock and roll history, possible.
10:56What is a guitar pickup?
10:57Well, it basically picks up the sound created by six strings and a set of fingers
11:02and sends it down a cable until it's blasted out of an amplifier,
11:05set at a very high volume, hopefully,
11:07causing your neighbors to either complain or call the police.
11:09Well, how does it do that?
11:11Well, that's right, magnets again.
11:13A guitar pickup comprises one or more magnets inserted into a bobbin
11:17and wound with conductive wire,
11:19which then transforms string vibrations into electrical energy,
11:22which flows into the guitar amp,
11:24where it's transformed back into mechanical energy as sound waves.
11:28And this is based on the principle of electromagnetic induction,
11:31discovered by English scientist Michael Faraday,
11:34who may not have realized at the time he was also inventing something called Jimi Hendrix.
11:44Lathe machines are used in a variety of different industries,
11:47usually to produce very specific components for bigger pieces of machinery.
11:52But what we're interested in is the magnet-based part of these machines,
11:56known as the magnetic chuck.
11:58A magnetic chuck provides a consistent clamping pressure
12:01to ensure there's no variation in how tightly or loosely a workpiece is held,
12:05thereby providing precision machining,
12:07cutting, drilling, milling, turning, and grinding,
12:10and ultimately improving the working safety of the lathe operator.
12:14Mechanically clamping these parts in place can cause direct distortion to the material,
12:18which the magnetic chuck completely avoids,
12:21and significantly reduces the time spent clamping and releasing items.
12:24And when you're producing engineering components on an industrial scale,
12:27every second counts.
12:29Overall, a magnetic chuck, although a modest part of the overall lathe machine,
12:33is possibly the most vital and important element of the entire thing.
12:37Magnets, eh? What would we do without them?
12:44Magnets are, of course, used in all sorts of machines in food production lines.
12:48But in common with the agricultural and mining industries,
12:51the most important use they have when it comes to the safety of potential customers
12:55and to prevent food manufacturers being sued by every consumer in the world,
12:59is removing impurities.
13:01During the production process, metal parts can enter products such as baby food,
13:06fruit juice, frozen or canned vegetables, spices, flour, sauces, grain,
13:10powdered milk, sugar, or chocolate. You name it!
13:12If it wasn't for these devices to remove this stuff,
13:15you could end up with more metal in your diet than the average robot.
13:18Iron particles in products like yogurt, cheese spread, and desserts
13:22can be captured by hygienic magnetic filters using neodymium magnetic bars,
13:26and fatty powders such as milk and egg powder can also accumulate on them.
13:31Iron contamination can also be present in cocoa beans,
13:34with nails and other metal objects falling in amongst them during harvesting.
13:38And these are removed by a magnetic drum separator, bullet magnet,
13:42cascade magnet, plate magnet, or external pole magnet
13:45before the cocoa beans are ground into powder.
13:48Once again, magnets have saved the day, not to mention our health.
13:53Number 3. The World's Most Powerful MRI Machine
13:57I could have mentioned any MRI whatsoever for this place on our list,
14:01because given their ability to spot otherwise invisible illnesses and conditions,
14:05countless lives have been no doubt saved across the globe.
14:08And if that's not good enough reason for it to be on our list of amazing magnetic machines,
14:12then I don't know what is.
14:14This MRI machine, however, is far from average.
14:17In fact, this is the largest MRI machine in the world.
14:21Known as ESULT, this incredible machine was created after 20 years of research
14:25by the French Atomic Energy Commission and German manufacturer Siemens.
14:29But let's talk about the magnets involved in this thing.
14:32ESULT's power surge peaks at 11.7 Tesla,
14:35and when you consider that the average MRI machine peaks at 3 Tesla,
14:39that's one hell of a jump.
14:41In fact, it's the equivalent of 230,000 times the Earth's magnetic field.
14:46It took 6 years to manufacture the incredible magnet,
14:49not to mention assembling the thousands of kilometers of niobium-titanium alloy
14:53that make up the machine's 45-ton coil.
14:56And if you think that sounds insane, then get this.
14:59The magnet needs to be maintained at a temperature of minus 271 degrees Celsius,
15:04that's close to absolute zero,
15:06which is achieved by using thousands of liters of liquid helium.
15:09Now that's what I call a magnet.
15:15It simply has to be on our list, right?
15:18With possibly the most well-known science experiment currently active,
15:21the LHC, or Large Hadron Collider,
15:24is the world's largest and most powerful particle accelerator
15:27and consists of a 27-kilometer ring of superconducting magnets.
15:31Since the LHC first roared into life back in 2008,
15:34high-energy particle beams have been flying around it at just under the speed of light
15:38in completely opposite directions,
15:40guided by the strong magnetic field created by these incredible electromagnets.
15:45Similar to the world's biggest MRI machine,
15:47these magnets need to be chilled to minus 271 degrees Celsius,
15:51once again using liquid helium,
15:53and resulting in the magnets being officially colder than outer space.
15:56Thousands of magnets are used to direct the beams around the accelerator,
16:00including 1,232 dipole magnets, which bend the beams,
16:04and 392 quadrupole magnets, which focus the beams.
16:08Crucially, magnets are also used to squeeze the particles closer together
16:13to increase the chances of collision,
16:15which is exactly what you need when you're trying to unlock the mysteries of the universe.
16:20Number 1. ITER
16:22Well, we couldn't really finish this list any other way, could we?
16:26This, ladies and gentlemen, is the most powerful magnet in the world.
16:29The central solenoid, known as the beating heart of the machine,
16:33is a magnet at the center of the world's largest fusion reactor, ITER,
16:37and produces a magnetic field measuring 13 teslas,
16:41280,000 times stronger than the one made by Earth.
16:44This means that the 59-foot-tall, 14-foot-wide central solenoid
16:48is not only as tall as a four-story building and weighs 1,000 tons,
16:52but it's also strong enough to lift an entire aircraft carrier,
16:55which generally weighs around 100,000 tons.
16:58In other words, this thing is big.
17:00The ITER experiment, which involves the internal collaboration of 35 countries,
17:05aims to prove the feasibility of sustained nuclear fusion to create energy,
17:09and the central solenoid is known as the beating heart
17:12because it will allow scientists to control the normally unstable reactants of nuclear fusion.
17:17Nuclear fusion has already been achieved inside several reactors, you see,
17:21but only ever for a few seconds at a time,
17:24and that's where the beating heart of the machine comes in.
17:26For nuclear fusion to become a viable option for generating electricity,
17:30this reaction must be maintained at a constant rate
17:33and require less energy to produce than it generates,
17:36and that's the highly ambitious hope for this creation.
17:39In the end, it's ever so slightly more powerful than those magnets on your fridge.
