The drawing shows a top view of two circular coils ofconducting wire lying on a flat surface. The centers of the coilscoincide. In the larger coil there are a switch and a battery. Thesmaller coil contains no switch and no battery. Describe theinduced current that appears in the smaller coil when the switch inthe larger coil is closed. (a) It flows counterclockwise forever after the switch isclosed. (b) It flows clockwise forever after the switch is closed. (c) It flows counterclockwise, but only for a short period justafter the switch is closed. (d) It flows clockwise, but only for a short period just after theswitch is closed.
