Question

A square loop of wire with side length 0.68 m contains a 94 N resistor, and is moving with constant speed into a region with a uniform 0.06 T magnetic

field. The loopis moving in the plane of the page at speed 1.9 m/s, and the magnetic field direction is into the page, as indicated in the diagram below. Calculate the current in the loop, and its direction (take clockwise as positive, and counterclockwise as negative). Give the value in millamperes (mA), to 2 decimal places, with positive for clockwise current, and negative as counterclockwise current.
