A long, straight wire carries a current I1=3.8 A and is distance h=17.4 cm from a rectangular current loop that carries a current I2=1.8 A.
(a) if the loop has a length L= 48 cm and a width w=23 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?
