A current elemetns of 0.2 A m is fixed at the centre of a circle of radius 10 cm . Another element of strength 0.5 A m is placed along the circumference and moved round the circle. At which positions will they sent maximum force on each other? Calculate these forces.

Text Solution

Verified by Experts

The correct Answer is:
