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

Options

  1. Avarying electric field
  2. Bvarying magnetic field
  3. Cthe iron core
  4. Dheat produced in the coil

Correct answer

B. varying magnetic field

Step-by-step solution

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.
