Magnetic field in perfect conductor

  1. May 8, 2010 #1
    Why in perfect conductor magnetic field B vanishes? It's often assumed while
    considering wave guides.

    Induced currents equal to the magnetic field flow on the exterior of the perfect conductor and prevent the field from extending into the conductor.

    Only oscillating magnetic fields vanish in a perfect conductor.
    A static magnetic field is possible.

    But not in super conductors. However, super conductors have a slightly different set of properties than perfect conductors but I have seen people confuse the two.
