We move a square loop of wire 2.1 cm on a side into a region of uniform magnetic field of 1.0 T with the plane of the loop perpendicular to the direction of the field. The loop is moving with a constant velocity of 2.0 m/s into the field region starting from a point outside the field. If the loop has a resistance of 3 ohms, find the force on the loop as it just enters the magnetic field region. (Enter the magnitude.)
