Weight changes under strong, uniform magnetic fields?

Click For Summary
SUMMARY

This discussion centers on the investigation of reversible weight changes in materials subjected to strong, uniform magnetic fields, particularly in the context of nuclear magnetic resonance imaging (MRI) and spectroscopy. The inquiry highlights the potential subtlety of such effects, suggesting that if they exist, they have not been widely recognized. The mention of the Gouy balance indicates a method for measuring magnetic susceptibility, which could be relevant in this context. The discussion raises questions about whether the magnetic fields used in NMR and MRI are sufficient to align nucleons in atomic nuclei, beyond just the alignment of electrons.

PREREQUISITES
  • Understanding of nuclear magnetic resonance (NMR) principles
  • Familiarity with magnetic susceptibility and the Gouy balance method
  • Knowledge of atomic structure, specifically nucleons and electrons
  • Basic concepts of magnetic fields and their effects on materials
NEXT STEPS
  • Research the principles of nuclear magnetic resonance (NMR) and its applications in material science
  • Explore the Gouy balance method for measuring magnetic susceptibility
  • Investigate the effects of strong magnetic fields on atomic nuclei alignment
  • Examine existing studies on weight changes in materials under magnetic fields
USEFUL FOR

Researchers in material science, physicists studying magnetic properties, and professionals in medical imaging fields such as MRI technicians and radiologists.

Has anyone ever looked for reversible weight changes while materials are subjected to uniform, strong magnetic fields, such as those involved in nuclear magnetic resonance imaging (MRI) or spectroscopy? I suspect no one ever has, for lack of a reason, and any such effects would have to be subtle, else someone would have noticed by now.

Interesting info. Are the magnetic fields typically employed here strong enough to cause nucleons in the atomic nuclei to line up (as in NMR/MRI), rather than just the atoms' electrons?
