Question

The magnetic dipole moment (μ) of a coil depends on the current (I), the area of the coil (A), and the number of loops (N). Rank the three different coils of wire shown figure below in order by the magnitude of their magnetic dipole moment.

Rank the coils from greatest to least magnetic dipole moment. If the coils have the same magnetic dipole moment, place them on top of each other.
