Question

Two identical circular coils A and B are kept on a horizontal tube side by side without touching each other. If the current in the coil A increases with time, in response, the coil B 

(a) is attracted by A

(b) remains stationary

(c) is repelled

(d) rotate

Answer 1

Correct option (c) is repelled

Explanation:

yes, it is true it is repelled by A current in A increases with time so there will be change of flux in coil B which will induce a current in B the direction of induced current in B will be opposite to direction of current in A and if the two loops carry current in opposite direction they repel each other.
