a force is exerted on current carrying conductor. the direction of force depends on both the direction of the current and the direction of magnetic field. this force is maximum when the direction of current is perpendicular to the direction of magnetic field
1. by which we can determine the directiona force exerted on current carrying conductor.
2 by which electrical equipment this principle is used.
3. write the working of the equipment in brief.
Answers
(1) We can determine direction of force by Fleming's Left Hand Rule
(2) This principle is used in electric motors.

When electric current is passed into the rectangular coil, this current produces a magnetic field around the coil.
The magnetic field of horse shoe-type magnet then interacts with the magnetic field of the coil and causes the coil to rotate continuously.
If ABCD is in horizontal position current from battery enters the coil through brush B _{ 1 }, and commutator half ring C:. The current flows in the direction ABCD
and leaves via ring and brush B _{ 2 }
The direction of current is from A to B, the direction of current is from C to D. The force on side AB of the coil is in the downward direction. Whereas the force on the side CD of the coil is in the upward direction. ABCD rotate in anti-clockwise direction.
While rotating when the coil reaches vertical position then the brushes B _{ 1 } and B _{ 2 } will touch the gap between the commutator rings and current to the coil is cut off. But the coil does not stop rotating because it has already gained momentum.
The coil CD comes on the left side and AB comes to the right side. Again they come in contact with brush B _{ 1 } Current direction is reversed.
The reversing of current in the coil is repeated after every half rotation due to which the coil continue to rotate as long as current from the batter is passed through it. The rotating shaft of electric motor can drive a large number of machines which are connected to it.
