Two different loops are concentric and lie in the same plane. The current in the outer loop is clockwise and increasing with time. The induced current in the inner loop then, is 
 

Given data:

Different loops having concentric radii

Concepts used: Mutual inductance

Explanation:

A current is induced in the inner loop counterclockwise. According to Lenz's Law, an induced electromotive force will always result in a current whose magnetic field opposes the changing magnetic flux.
