Answer 1

Answer:

Definition: Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. Experiment: Two different coils of copper wire having large number of turns (say 50 and 100 turns respectively) are taken.

The principle behind the electric motor is based on Fleming's left hand rule. Working: When a current is allowed to flow through the coil PQRS the coil starts rotating anti-clockwise. ... These two forces cause the coil to rotate anti-clockwise. When coil complete half rotation, the position of PQ and RS interchange.
