The mass per unit length of a 14-gauge copper wire is 18.5 g/m. If the wire is placed running along the horizontal x-axis (east-west) in a region in which there is a uniform 0.423-T magnetic field directed along the horizontal y-axis (northward). Calculate the magnitude of the minimum current in the wire that could cause the wire to levitate (i. e., have the force of its own weight canceled by a vertically upward magnetic force on it.)
