    In the same way that turning on a light is a short...

    The coiled wire with DC current running through it will magnetise the object in the centre. Don't use the screwdriver across the terminals just the wire.

    Yes it will sparkle a bit but it only takes breif contact to develop the magnetic field, you won't need to hold it on the battery for more than a moment.
    Dropping/hitting it will usually lose it's magnetism.

    Nope, AC will de-magnetise, and cause lots of sparks/smoke etc

    I have never tried it but leaving metal exposed to a magnet for a perid of time does the same thing doesn't it? Or am I just mad?

    I have a few small magnets lying round and thought of using epoxy to fit one on the top of the plug but would worry about it coming loose in the box.
