Figure P21.61 shows four configurations of a wire loop placed near a long, straight wire with a time-varying current. Determine the direction of
(a) the induced magnetic field in the wire loop (into or out of the page) and
(b) the induced current (clockwise or counterclockwise) for each configuration (1) through (4).
