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.
E. No, the net force on the magnet is zero.
