Whenever, current is changed in a coil, an induced e.m.f. is produced in the same coil. This property of the coil is due to

1. mutual induction
2. eddy currents
3. self induction
4. hysteresis

Correct answer: self induction

Solution

When the current in a coil changes, the magnetic field it creates also changes, inducing an emf in that same coil. This phenomenon is called self induction.
