A copper wire (density ? = 8960 kg/m3) of radius 0.449 mm is carrying a current at the Earth's Equator. Assuming that the magnetic field of the Earth has magnitude 0.515 G at the Equator and is parallel to the surface of the Earth and that the current in the wire flows toward the east, what current is required to allow the wire to levitate?
