Problem
Three identical bar magnets lie in a straight horizontal line with equal center-to-center spacing. The two outer magnets are fixed so that their north poles face the middle magnet. The middle magnet is oriented with its north pole facing the magnet on the left. Which of the following describes the initial net force on the middle magnet?
(a) A force to the left, toward the left magnet
(b) A force perpendicular to the line of magnets (out of or into the page)
(c) A force to the right, toward the right magnet
(d) No net translational force; the forces cancel but a torque may be present
