A long horizontal wire carries a current of 45 A. A second wire, made of 2.5 mm diameter copper wire and parallel to the first but 15 cm below it, is held in suspension magnetically. What is the magnitude of the current in the lower wire?
A 2.5 mm diameter copper wire carries a 48 A current. Determine the magnetic field inside the wire, 0.556 mm below the surface.
