    Yeah... that would've been me. Okay, that was indeed a bold statement ;-)

    Not being aware of readily available degaussers, I would think the magnetic
    field neccessary will induce an electric field in the electronics of the
    drive that will be enough to kill the circuits. As for my statement "killing
    the operator", I'm afraid I had some visions of someone experimenting with
    tesla coils and very high capacity discharges. They were probably uncalled
    for. ;-)
    I think that it is unwise to expose the human body to very strong magnetic
    fields but, granted, if you do not hold the degausser to your chest or
    against your skull you'll probably be just fine. ;-)

    Quote: "Do not operate the degausser if you have a pacemaker."
