Three identical coils A, B and C are placed with their planes parallel to one another. Fig Coils B and C carry currents as shwon. Coils B and C are fixed. The coil A is moved towards B with uniform speed. Is three any induced current in B

Text Solution

Verified by Experts

As coils B and C fixed, there is no induced current in B due to C. However, when A is moved towards B, an e.m.f. is induced in B, which would oppose relative motion of A towards B. As current in A is clockwise, induced current in B must be anticlockwise.
