Imagine a wire with linear mass density $2\mathrm{.}12$ g$/$m encircling the Earth at its magnetic equator, where the field is modeled as having the uniform value $29\mathrm{.}0$T horizontally north. What magnitude and direction of the current in the wire will keep the wire levitated immediately above the ground?
