00:00Electric motor is used in many devices like pumps, baby toys, toothbrushes, and in fans.
00:07Do you want to know how an electric motor works?
00:10It changes electrical energy into mechanical energy.
00:14An electric motor has rectangular coil of isolated copper wire.
00:19The coil is placed between north and south poles of a magnetic field.
00:24End of the coil has two halves of the split rings.
00:27The internal side of these halves is insulated and attached to an excel.
00:33The outer conducting ends touch two stationary brushes.
00:37Current from the battery enters into the coil by the help of conducting brushes and flows back in the battery by other brush.
00:44By using Fleming's left-hand rule to find the direction of the force on a current-carrying conductor in a magnetic field we find the force acting on the arm.
00:53EF pushes it downward and force applying on arm.
00:57G, H pushes it upward.
00:59So, the magnetic coil is free to move about an axis and rotate anti-clockwise.
01:06After half rotation Q make contact with the brush and P with brush Y.
01:10Now the current in the coil gets reversed and flows along the path H, G, F, E due to reversal of the current also changed the direction of the force acting on the two arm, EF and G, H.
01:23Thus, the arm E, F of the coil that was previous pushed down is now pushed up.
01:28And the arm, G, H earlier pushed up, is now pushed down.
01:34Therefore, the coil and excel rotate half a turn more in the similar direction.
01:38The reversing of the current is repeated at each half rotation giving rise to a continuous rotation of the coil and the excel.
01:46In this way an electric motor works.
01:49In this way an electric motorë°© takes place.
01:50In this way, take care of the silicone pedal will become more in the same diameter.
01:53And everything else is 길 001,030.
01:54At each half rotation is life by counting andериal of the pilots.
