Electromagnetic Coil Strength from Moving Liquids?

Click For Summary
SUMMARY

The discussion centers on the potential of using charged fluids, such as those in oil-based van de Graaff generators, to generate stronger magnetic fields compared to traditional copper coils. The author references a drift velocity of 8.4 cm/hr for electrons in 12 AWG wire at 100VDC and proposes that a charged fluid could achieve a velocity of 507042.25 cm/hr, resulting in a magnetic field approximately 60362.17 times more powerful than that of copper wire. Key questions raised include the feasibility of this approach and the relationship between charge density and the voltage applied to the fluid.

PREREQUISITES
  • Understanding of drift velocity in electrical conductors

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?
