Electromagnetic Coil Strength from Moving Liquids?

  1. Jan 9, 2015 #1
    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?
