The phenomenon of producing emf in a coil due to the change of current in itself is called:
Correct answer: A. Self induction
- A. Self induction
- B. Mutual induction
- C. Inductance
- D. Both (a) and (b)
Explanation
The phenomenon of producing an electromotive force (emf) in a coil due to the current change is called self-induction. It refers to the phenomenon where a changing current in a coil induces an electromotive force (emf) in the same coil. Faraday's law of electromagnetic induction governs it and occurs when the magnetic field around a coil changes due to a change in the current flowing through it.

About Electromagnetic Induction
Changing magnetic flux induces an emf according to Faraday's law, while Lenz's law gives the direction that opposes the change producing it. Transformers apply induction between coils to step alternating voltage up or down, with turns ratio, current transformation and energy losses determining practical operation.
