Different ways to induce current in a coil are as given below : (i) If a magnetic field is changed around a coil, an induced current is set up in the coil. (ii) If a coil is moved in a magnetic field, an induced current is set up in the coil. (iii) If a coil is rotated in a uniform magnetic field, iRead more

(iii) If a coil is rotated in a uniform magnetic field, it produces an induced current in the coil.
In an electric motor, the split ring acts as a commutator. Due to its action, the direction of current flowing in motor coil reverses after every half turn, giving rise to a continuous rotation of the coil and the axle.

An electric motor is based on the principle that a current- carrying conductor experiences a force when placed in a magnetic field. If the direction of the magnetic field and that of the current are mutually perpendicular then the direction of the force is given by fleming's left-hand rule.

The compass needle is a small bar magnet. When a compass needle is brought near a bar magnet than due to repulsive force between like poles and attraction between unlike poles, the compass needle is deflected. Finally, the compass needle comes to rest in the direction of net magnetic field.
