Electromagnetic effect on gases

  1. Jul 15, 2015 #1
    Are there any research or paper regarding electromagnetic effect on gases. For example does H2 gas physically move under electromagnetic field?

    H2, being both a neutral and non-polar molecule, doesn't respond to electric fields unless they are high enough to ionize the molecule. In addition, it is a weak diamagnetic material and is very, very slightly repelled by a magnetic field. For most practical purposes, no, H2 gas doesn't move under the influence of electromagnetic fields.

    Thank you for your reply. MRI scanning machines use superconducting electromagnets to align the H2 molecules in a human body in water form. So with super conducting high magnetic ( as even mentioned by you in your earlier reply) is it possible to move the H2 in gaseous form. If No then are any other paramagnetic/diamagnetic gases able to move (attract/repel) under superconducting magnetic fields. Actually a video online has explained this, The link is " https://www.khanacademy.org/science...ions-jay-sal/v/paramagnetism-and-diamagnetism" seeing this video i was wondering if any gases move due to electromagnetic effect ( high field probably)?

    In a field of 1 Tesla at what velocity will oxygen gas molecules be pulled? What is the force acting on O2 molecules. Do we have any formula to calculate this?
