Imagine placing a magnet in a uniform magnetic field (a field whose vectors have the same magnitude and direction at all points). Will the field exert a net force on the magnet (that, is, a force that causes the magnet's center of mass to accelerate)? If so, in what direction? (Hint: Use the dipole analogy.)
A) Yes, in the direction of the magnetic field.
B) Yes, opposite to the magnetic field's direction.
C) Yes, in a direction perpendicular to the magnetic field.
D) Yes, in a direction that depends on the magnet's orientation relative to the field.
E) No, the net force on the magnet is zero.

In a uniform magnetic field, the forces on the opposite poles of a magnet (considered as a magnetic dipole) are equal in magnitude but opposite in direction, resulting in no net force on the magnet. However, there could be a torque that aligns the magnet with the field.
