The phenomenon in which an electric current is induced in a conductor by a varying magnetic field is called _______.

Asked in GSEB Board March 2016 · Applications and conceptual

Answer: (3) Electromagnetic induction

Step-by-step solution

Idea: Faraday found that whenever the magnetic flux through a closed circuit changes, a current flows in it.

That current is called the induced current, and the emf that drives it the induced emf.

The phenomenon itself — producing an emf and current by a changing magnetic field — is called electromagnetic induction.
