A rectangular loop of dimensions $l = 20$ cm and $w = 10$ cm moves with a constant velocity $v = 2$ m/s away from a long wire that carries a current $I = 5$ Amps in the plane of the loop. The total resistance of the loop is $R = 10$ Ohms. Find the current in the loop at the instant the near side is a distance $r = 15$ cm from the wire.
