A square filamentary loop of wire is 25 cm on a side and has a resistance of 125  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 × 10⁸t −0.5x)μT. Develop a function of time that expresses the ohmic power being delivered to the loop.
