All of the following charge-movement configurations would produce a magnetic dipole moment except
A) charge flowing in a circle.
B) charge flowing radially outward (with spherical symmetry) from a central point.
C) charge flowing along the perimeter of a "loop" with square corners.
D) Hold it! There are no exceptions.

Question

Quizplus · Accepted Answer

A magnetic dipole moment is produced by the motion of electric charge in a looped path. Options A and C involve charge moving in closed loops (circular and square, respectively), which would generate a magnetic dipole moment. However, option B, where charge flows radially outward in a spherically symmetric manner, does not involve a looped path and thus would not produce a magnetic dipole moment.
