A wire near the equator carries a current perpendicular to the Earth's magnetic field of $50\mathrm{\mu }\mathrm{T}$ in a location where the field is parallel to the ground and points straight north. Assuming it was of correct magnitude, what direction should the current be in to levitate the wire?
