Coloured Magnetic Gas?

[Sputnik-1]

Howard Johnson states that magnetic fields are 3 dimmensional vortexes - not 2 dimmensional flat planes as the paper and iron filings experiment suggests.

Would it be possible to create a coloured magnetic gas that would highlight the magnetic vortex fields in real time as an experiment takes place?

I visualise a clear perspex case with said experiment inside. A coloured magnetic gas could be injected into the case and the magnetic gas should be attracted to the spirals of the magnetic vortex, and show those magnetic fields in a 3 dimmensional plane.

This would have the benefit of performing experiments with magnetic and electric fields, and being able to get real time visual feedback during the experiment.

Where have I have heard that intro and out-tro music (can we call it music?, I guess so ) before?

Thanks for those links.

The ferro-fluid pictures show that magnetic fields are complex patterns.

The blue plasma experiment looked interesting as well. At least 2 types of plasma there.

The excited neon gas is most like what I have in mind.

It would be nice to encase a working experiment with something like the neon gas, and watch how it highlights the complex magnetic fields. Notice how just a slight variation of the neodymium magnet caused the neon gas to respond in different ways?

This is why I'd like to visualise how these fields are changing in real time, with a magnetic gas.

The sort of parameters that could be altered during an experiment could be things like DC pulsed frequency, and different AC high frequency low voltages.

Other things like physical characteristics of the proximity of components could be tested with real time feedback.  It would be interesting to see the magnetic fields for how things like the MEG TPU work.
