Find the current necessary to float the wire

Reference no: EM13539230

A straight, stiff, horizontal wire of length 30 cm and mass 60 g is connected to a source of emf by light, flexible leads. A magnetic field of 1.5 T is horizontal and perpendicular to the wire. Find the current necessary to float the wire; that is, find the current so the magnetic force balances the weight of the wire. Answer in units of A
