Electromagnetic Coil Strength from Moving Liquids?

AI Thread Summary
The discussion explores the potential of using charged fluids, like those in oil-based van de Graaff generators, to generate stronger magnetic fields compared to traditional copper coils. It highlights that while electron velocity in copper wire is slow, moving ions in a fluid could achieve significantly higher velocities, potentially leading to much more powerful magnetic fields. The conversation raises questions about the feasibility of this concept and the relationship between charge density and the voltage applied to the fluid. Participants are interested in understanding the charge density achievable with ionic fluids and how it relates to their magnetic field strength. The inquiry seeks to clarify whether the theoretical advantages of using ionic fluids are practical or if there are limitations to consider.

I was reading about drift velocity and according to http://amasci.com/miscon/speed.html 100VDC at 1A moving through ~12 AWG wire would produce an electron velocity of 8.4 cm/hr. Since that is incredibly slow I'm curious if a charged fluid (something like the oil used in an oil-based van de graff generator with an external high-voltage charge applied to it to) could be used to generate a much more powerful magnetic field than is possible with a copper coil? Something on the order of 507042.25 cm/hr (6L/min in 3/8" ID tubing) could easy be attained with the same wattage of off the shelf components suggesting if the mobile ions are the same the coil would produce a field ~60362.17 times more powerful than a copper wire. Am I missing something here or is this feasible?

What charge density can you accomplish with your ionic fluid? Electron density is not dependent on macroscopic ionized molecules.

Where might I find that information? Is it related to the voltage the fluid is charged to?
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
