Question 275: Electromagnetic Induction

Question

The alternating e.m.f. induced in the secondary coil of a transformer is mainly due to

Accepted Answer

The secondary coil experiences an emf as a result of the changing magnetic field. Therefore, a changing magnetic field is primarily responsible for the transformer voltage that is induced in a transformer's secondary coil.
