Consider a compass with a square magnet placed in a uniform electric field, as shown below.

If the magnet is free to pivot around an axis pointing toward the viewer that goes through the point at the magnet's center, which way will it turn (if it does) in this field?
A) Clockwise, to align itself with the field.
B) Counter clockwise, to align itself with the field.
C) $180^{\circ}$ either clockwise or counter clockwise.
D) It won't turn, as it is already aligned with the field.
E) It won't turn, because the field wants to twist it around a different axis altogether.
F) It won't turn because it is not affected by this field.
