Is it possible to move air using a magnetic field?

  1. Dec 30, 2013 #1
    Is it possible to move air using a strong enough magnetic field? Let's say for something like a fan.

    If so, what's the physics behind how that would work, and how would you quantify how strong the magnetic field would need to be?

    I thought MHD requires a conductive medium, such as salt water or plasma.

    Are you saying MHD can be applied to air at normal temperatures and pressures?

    If you ionize the air you can do it, for example using dielectric discharge plasma, which is a non-thermal plasma at nearly ordinary room temperature and pressure and is cheap and easy to produce.
