Question

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 0.288-T magnetic field directed along the horizontal y-axis (northward). Calculate the magnitude of the minimum current in the wire that could allow the wire to levitate if the conventional current points to the east.
