A conducting bar slides without friction on two parallel horizontal rails that are 50 cm apart and
connected by a wire at one end. The resistance of the bar and the rails is constant and equal to 0.10
. A uniform magnetic field is perpendicular to the plane of the rails. A 0.080-N force parallel to
the rails is required to keep the bar moving at a constant speed of 0.50 m/s. What is the magnitude
of the magnetic field?
