Discussion Overview

The discussion revolves around how to visually represent a nuclear magnetic octupole moment for a presentation aimed at an audience with varying levels of physics knowledge. Participants explore different illustrative approaches and the challenges of conveying complex concepts simply.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant suggests using a pear-shaped nucleus to represent octupole deformations, but questions the appropriateness of this for depicting the magnetic field rather than the deformation itself.
  • Another participant proposes using an existing image of electric multipoles as a basis for magnetic multipoles, suggesting labeling the poles of bar magnets instead.
  • A third participant comments on the imperfection of both the pear shape and the representation of nucleons, emphasizing the need to focus on key issues in the presentation.
  • There is a mention of P-orbitals and their role in aligning magnetic domains, particularly in materials like ferric metals under strong magnetic fields, though its relevance to the octupole moment illustration is not clear.

Areas of Agreement / Disagreement

Participants express differing views on the best way to visually represent the nuclear magnetic octupole moment, indicating that no consensus has been reached on a definitive approach.

Contextual Notes

Participants acknowledge the complexity of accurately depicting nuclear magnetic moments and the limitations of simplified illustrations for a general audience.

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.
