The phenomenon of production of induced emf is called:
Correct answer: B. Electromagnetic induction
- A. Magnetic induction
- B. Electromagnetic induction
- C. Both (a) and (b)
- D. None of these
Explanation
This option correctly identifies the phenomenon as "electromagnetic induction," which refers to the process by which a changing magnetic field induces an electromotive force (EMF) in a circuit. This phenomenon is a fundamental concept in electromagnetism, as described by Faraday's law of electromagnetic induction.

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.
