- In Figure, a metal wire of mass m=24.1mg can slide with negligible friction on two horizontal parallel rails separated by distance d=2.56 cm. The track lies in a vertical uniform magnetic field of magnitude 56.3 mT. At time t=0, device G is connected to the rails, producing a constant current i=9.13 mA in the wire and rails (even as the wire moves). At t=61.1 ms, what are the wire’s (a) speed and (b) direction of motion (left or right)?
