In the figure, a metal wire of mass m = 28.3 mg can slide with negligible friction on two horizontal parallel rails separated by distance d = 1.73 cm. The track lies in a vertical uniform magnetic field of magnitude 61.4 mT. At time t 0 s, device G is connected to the rails, producing a constant current i = 9.88 mA in the wire and rails (even as the wire moves). At t = 70.3 ms, what are the wire's (a) speed and (b) direction of motion?

A metal rod of mass m slides without friction along two parallel horizontal rails, separated by a distance and connected by a resistor R, as shown in Figure P30.13. A uniform vertical magnetic field of magnitude B is applied perpendicular to the plane of the paper. The applied force shown in the figure acts only for a moment, to give the rod a speed v. In terms of m, , R, B, and v, find the distance the rod will then slide as it coasts to a stop. Figure P30.13
Assume the region to the right of a certain plane contains a uniform magnetic field of magnitude 1.00 mT and the field is zero in the region to the left of the plane as shown in Figure P22.71.

(b) Assuming the maximum depth of penetration into the field is 2.00 cm, find the kinetic energy of the electron.
