When the magnitude of the B field in the magnet is increased, does the U swing to the right or to the left, or does it remain at rest? Using the right-hand rule, we find that the magnetic force exerted O on the U-shaped wire points upward. Thus, the wire does not swing, but bends up when the field is turned on. Using the right-hand rule, we find that the magnetic force exerted O on the U-shaped wire points downward. Thus, the wire does not swing, but bends down when the field is turned on. Using the right-hand rule, we find that the magnetic force exerted on the U-shaped wire points to the left. Thus, the wire swings toward the left when the field is turned on. Using the right-hand rule, we find that the magnetic force exerted on the U-shaped wire points to the right. Thus, the wire swings toward the right when the field is turned on. Submit Request
