    Does anyone know of a substance that can block a magnetic field?

    Look up something called "mu metals".

    Caution: there are no practical material (of arbitrary thickness) that can shield magnetic field of arbitrary strength. So your question is rather vague.

    I've heard of one, I think it started with an I.

    Check the superconductors.
    (Not blocking but an interesting effect!)

    I've found such an interesting question on this website,
    http://www.newton.dep.anl.gov/askasci/phy00/phy00508.htm

    It is also very helpful for my little knowledge about the magnetic field. So thanks for the question :smile:
