Problem
A U-shaped magnet is fixed to a table with its north pole on the left prong and south pole on the right prong. A bar magnet is held directly between the prongs so that its north pole faces the midpoint between the prongs and its axis is perpendicular to the line joining the prongs. Which of the following describes the initial net force on the bar magnet when it is released?
(a) It remains stationary because forces from the two prongs cancel exactly.
(b) It moves toward the right prong of the U-shaped magnet.
(c) It moves toward the left prong of the U-shaped magnet.
(d) It experiences only a torque that rotates it but causes no net translation.
