Question

A thin rectangle coil lies flat on a low-friction table. A verylong straight wire also lying flat on the table, a distance z fromthe coil, carries a convetional current I to the right as shown,and this current is decreasting: I = a-bt, where t is the time inseconds, and a and b are positive constants. The coil has width wand height h, where h << z. It has N turns of wire with totalresistance R.

What are the intial magnitude and direction of the nonzero netforce that is acting on the coil? Explain in detail. If you mustmake simplifying assumptions, state clearly what they are, but bearin mind that the net force is not zero.
