15. The magnitude of the net force acting on the coil is?

P24 A thin rectangular coil lies flat on a low-friction table t (Figure 22.75). A very long straight wire also lies flat on the table, o a distance z from the coil. The wire carries a conventional current 1 to the right as shown, and this current is decreasing: I- a -bt, a where t is the time in seconds, and a and b are positive constants. 1 The coil has length L and width w, where w 《 z. It has N turns of wire with total resistance R. 1=a-bi Figure 22.75 cail n ea F,-도
