It is possible with appropriately shaped external magnetic poles to create a situation where the effect of those poles does not vary with position along the SG axis. Imagine a small magnet placed in such a situation. What is the direction of the net force on the small magnet?
A) Upward.
B) Downward.
C) There is zero net force, no matter how the magnet is oriented.
D) The answer depends on the magnet's orientation.
E) None of the above (explain).

In a uniform magnetic field, the forces on the opposite poles of a small magnet are equal and opposite, resulting in no net force on the magnet regardless of its orientation. The magnetic field exerts forces on both poles of the magnet that cancel out, leading to zero net force.
