Answer Text:
Mutual induction
-Mutual induction is produced when two coils are placed close to each other and a changing current is passed through one of them which in turn produces an induced e.m.f in the second coil.
-Therefore mutual induction occurs when a changing magnetic flux in one coil links to another coil.
