A straight rod of mass m and length l can slide on two parallel plastic rails kept in a horizontal plane with a separation d. The coefficient of friction between the wire and the rails is ‘mu’. If the wire carries a current i, what minimum magnetic field should exist in the space in order to slide the wire on the rails?
