In the figure, a rectangular loop of wire with length a = 2.6 cm, width b = 1.2 cm, and resistance R = 0.79 m? is placed near an infinitely long wire carrying current i = 5.2 A. The loop is then moved away from the wire at a constant speed v = 5.6 mm/s. When the center of the loop is at distance r = 2.8 cm, what are (a) the magnitude of the magnetic flux through the loop and (b) the current in amperes induced in the loop?
