A 0.245-kg metal rod carrying a current of 10.5 A glides on two horizontal rails 0.480 m apart. What vertical magnetic field is required to keep the rod moving at a constant speed if the coefficient of kinetic friction between the rod and rails is 0.100?
Again I am supposed to use the formula F=IL x B. But I'm not sure where to start... What am I supposed to do with the coefficient of kinetic friction?
Any help would be great! thanks in advance! :)
