Apermanent magnet creates a magnetic field at the origin with strength bperm-1t. a current-carrying wire is oriented such that it creates a magnetic field at the origin that points in the same direction as the magnetic field from the permanent magnet. (a) what is the net magnetic field at the origin if the wire carries a magnitude of 1-2 a and is located a distance r = 5 cm from the origin? (b) if the current in the wire reverses directions, what is the new net magnetic field at the origin?
