Charges passing through a superconductor

  1. Jan 2, 2009 #1
    Hi

    I just wanted to know if a charge passing through a superconductor will diminish its current. I know superconductors will keep a current as long as they are kept cool, and I know that a moving charge will produce a magnetic field. However, will this produced magnetic field reduce the current in the superconductor if the charged particle flies through it? (I'm thinking of a ring of superconducting material and the charge passing through the middle)

    i think that depends on the temperature of the superconductor. the magnetic field of the charge, in most cases should disrupt the flow of the currently if slightly. But at low temperatures and according to the meissner effect the conductor should be diamagnetic with no magnetic field inside.
