A long, straight wire carries a current I1 = 3.5 A and is a distance h =15 cm from a rectangular current loop that carries a current I2 = 1.5 A.
(a) If the loop has a length L = 45 cm and a width w = 20 cm, what are the magnitude and direction of the force exerted by the wire on the loop?
(b) What is the force exerted by the current loop on the wire?
