A lab instructor performs a demonstration where a current-carrying wire is made to levitate. The wire has a mass per unit length of 0.460 g/cm and carries a current of 2.64 A horizontally to the south. Find the magnitude and direction of the minimum magnetic field needed to lift this wire vertically upward. (Enter the magnitude in T.) magnitude? T direction?
