Question

Name the current induced in solid metallic masses when the magnetic flux threading through them changes.

(a) Ampere currents

(b) Faraday currents

(c) Eddy currents

(d) Solenoidal currents

I have been asked this question in an interview for job.

The above asked question is from Electromagnetic Induction in division Electromagnetic Induction of Physics – Class 12

Answer 1

Right choice is (c) Eddy currents

To explain I would say: Eddy currents are the currents induced in solid metallic masses when the magnetic flux threading through them changes. These currents look like eddies or whirlpools in water and so they are known as eddy currents.
