Magnetic field due to currentEasy
Question
A metal wire of mass ′m′ slides without friction on two rails spaced at a distance ′d′ apart. The track lies in uniform vertical magnetic field ′B′. A constant current I flows through the wire. The velocity of the wire as a function of time ′t′. (Assume the wire is to be rest initially) :-
