In the figure, a metal wire of mass m = 28.2 mg can slide with negligible friction on two horizontal parallel rails separated by distance d - 2.87 cm. The track lies in a vertical uniform magnetic field of magnitude 46.0 mT. At time t = 0s, device G is connected to the rails, producing a constant current i = 5.94 mA in the wire and rails (even as the wire moves). At t = 74.6 ms. what are the wire's (a) speed and (b) direction of motion?
