Concept

Problem: Two closed loops A and C are close to a long wire carrying a current IWhile I is decreasing, what is the direction of the net force that the wire exerts on loop A?

FREE Expert Solution

If the current is decreasing, there will be induced current in loop A, which is in a clockwise direction.

Therefore, loop A gets an attractive force.
