I How to depict a nuclear magnetic octupole

[BillKet]

Hello! I am not sure if this is the best place for this question, but I want to make a simple illustrative drawing (for a presentation given to people both with and without physics knowledge) of a nuclear magnetic octupole moment. For example for a magnetic dipole I can use a magnet as a representation or for a quadrupole electric moment I can draw a rugby-ball like shape nucleus, but I am not sure what to use for a nuclear magnetic octupole moment. I saw people often use a pear shaped like nucleus for octupole deformations, but in this case it is not the deformation that is octupolar (or even the electric charge distribution), it is the magnetic field. Any advice about how can I easily (not necessarily super accurately) convey that image to a general audience? Thank you!

The picture below (https://www.eurekalert.org/multimedia/916524) depicts electric multipoles (red = + charges, blue = - charges). But you could use it just as well for magnetic multipoles by labeling red=N-pole, blue=S-pole of 1, 2, or 4 identical bar magnets.

The pear may not be perfect, but the collection of hard little balls (nucleons) with well-definied positions, momenta, and identities is even less perfect. Concentrate the presentation on the important issues.

P-orbitals, most likely to align domains within conglomerates, ex. ferric metals introduced to strong magnetic fields. They become magnetic.
