A positive charge is placed some distance in the -hat{i}
direction from the magnet. (Intro 1 figure) Assume that no charges
are induced on the magnet.
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) No torque at all
b) A torque only if onemagnetic pole is slightly closer to the charge than the other |
|
| c) A torque due to the charge attracting the south pole of the magnet d) A torque due to thecharge attracting the north pole of the manget |
