Magnetic field strength

  1. Dec 23, 2013 #1
    Now I'm sure one can find this at google somehow , even though I wasn't that successful with it.

    Does someone know what is the highest magnetic field strength for a givem size permanent magnet for example?
    Like a 1cm ball of neodymium or some other material, what would be the highest field strength possible to achieve for a given material of a given size?

    For permanent magnets, the limit is given by the saturation, and it does not depend on the size of the magnet. ~2T are possible, everything beyond that needs coils, lasers or other stuff.
