Chapter 9, Problem 9.9P

A square filamentary loop of wire is 25 cm on a side and has a resistance of 125 El per meter length. The Loop lies in the z = 0 plane with its corners at (0, 0, 0), (0.25, 0, 0), (0.25, 0.25, 0), and (0, 0.25, 0) at t = 0. The loop is moving with a velocity v_y = 50 m/s in the field B_z = 8 cos(1.5 Ă— 10⁸t - 0.5x) đ�œ‡T. Develop a function of time that expresses the ohmic power being delivered to the loop.
