Positive Charge Magnetic Fields: Real World Examples

[Windadct]

As a SP phenomena I thought this may be the best sub to post this.

We understand how current creates a magnetic field, and almost all forms of current are really electron flow. My question is - are there any known (real world) examples of positive particle flow, creating a magnetic field?

For example - if there is positive ion flow in an electrolyte - have people observed the expected / corresponding Magnetic field?

Or - if we have a positively charged piece of material, when we move it, can we easily detect the magnetic field it would create?

It seems like this should be "do able" but I have not seen it.

If - any examples of this being put to good use? ( Yes a positive charge in an accelerator is a case - but I am thinking of anything more commonly observed.)

It seems like you already have your answer.

I was thinking more that is commonly observable - in typical physics lab.

If you transform a current carrying wire into the rest frame of the electrons then the magnetic field must be due to the motion of the protons. Figure out the electron drift velocity, mount the wire on a cart and your magnetometer on the bench?

Why? Are you a physics educator preparing an exercise for students? If so, please see the link I posted in my previous reply. It includes a discussion about the magnitude of the fields detected.

Hi. We can make a leaf electroscope in our laboratory charged positive. Then try moving it near compasses.
