Question:

Part of a single rectangular loop of wire with dimensions shown in Fig. 21-51 is situated inside a region of uniform magnetic field of 0.550 T. The total resistance of the loop is 0.230 Ω. Calculate the force required to pull loop from the field (to the right) at a constant velocity of 3.40 m/s. Neglect gravity.
