A 0.300-kg metal rod carrying a current of 12.0 A glides on two horizontal rails 0.590 m apart and 2.0 m long. (a) If the coefficient of kinetic friction between the rod and rails is 0.160, what vertical magnetic field is required to keep the rod moving at a constant speed? (b) If the friction between the rod and rail is reduced zero, the rod will accelerate. If the rod starts from rest at the one end of the rails,...

c37. Review. A rod of mass 0.720 kg and radius 6.00 cm rests on two parallel rails (Fig. P29.37) that are d 四12.0 cm apart and L-45.0 cm long. The rod carries a L. current of 48.0 A in the direction shown. A magnetic field B of magnitude 0.240 T is directed perpendicular to the rod and the rails. The rod moves over the rails without friction. What is the acceleration of the rod? How fast is the rod moving...
