If the current in one coil becomes steady, the current in neighbouring coil  is?

(a) Zero

(b) Infinity

(c) Doubles

(d) Halves

I got this question by my school principal while I was bunking the class.

This interesting question is from Mutual Inductance in chapter Inductance in a DC Circuit of Basic Electrical Engineering

Best answer
Right option is (a) Zero

The best I can explain: A current is induced when there is changing magnetic flux. Hence the induced current in neighbouring coil is zero when the current is steady.
