What current is required to allow the wire to be suspended

Reference no: EM13320892

A current-carrying wire of length 0.5m is at the Equator. Assuming that the magnetic field of the Earth has magnitude of 5 x 10^-5 T at the Equator and is parallel to the surface of the Earth and that the current in the wire flows toward East, what current is required to allow the wire to be suspended? Assume the mass of the wire is 0.05 gram.
