The alternating e.m.f. induced in the secondary coil of a transformer is mainly due to
  1. varying electric field
  2. varying magnetic field
  3. the iron core
  4. heat produced in the coil

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.
