Your friend wants to be a magician and intends to use Earth's magnetic field to suspend a current-carrying wire above the stage. He asks you to estimate the minimum current needed to suspend the wire just above Earth's surface at the equator (where Earth's magnetic field is horizontal). Assume the wire has a linear mass density of 12 g/m, and the Earth's magnetic field strength is 5.0 x 10-5. Would you advise him to proceed with his plans for this act?
