A bar magnet oriented along the y axis can rotate about an axis parallel to the z axis. Its north pole initially points along j^. Assume that the length of the magnet is much smaller than the separation between it and the charge. As a result of magnetic interaction (i. e., ignore pure Coulomb forces) between the charge and the bar magnet, the magnet will
experience which of the following?

a. A torque due to the charge attracting the north pole of the magnet
b. A torque due to the charge attracting the south pole of the magnet
c. A torque only if one magnetic pole is slightly closer to the charge than the other
d. No torque at all
