Two parallel conducting rails with negligible resistance are 50.0 cm apart and are
connected together at one end by an 18.8-2 resistor. A conducting bar, also with negligible
resistance, is free to slide along the rails. The system is in a region where a 325-mT
magnetic field points perpendicular to the plane of the rails, as shown in (Figure 1).
