please help me I need the working of electric motor

balu143: Working principle of DC Motor mainly depends upon Fleming Left Hand rule. In a basic DC motor, an armature is placed in between magnetic poles. If the armature winding is supplied by an external DC source, current starts flowing through the armature conductors. As the conductors are carrying current inside a magnetic field, they will experience a force which tends to rotate the armature.

balu143: 1. In the coil, the current flows from A to B and the magnetic field is from north to south. Applying Fleming left hand rule, the direction of thumb points upwards, hence, the segment AB will tend to move upward, with a certain force.

NithishaSb: tq so much

balu143: 2. In the coil, the current flows from C to D and the magnetic field is from north to south. Applying Fleming left hand rule, the direction of thumb points downwards, hence, the segment CD will tend to move downward, with a certain force.

Thus, a couple acts on the coil, which turns the coil in clockwise direction.
