I got a small air pressure gauge for Christmas with the slime stuff to goop inside the tyre and fix a flat in emergency circumstances (read: any trip you're on with Lucy) and the thing has a little magnet on it. Its not the first gauge I have seen either with a magnet on it either, and I wondered this then too.......

What is this magnet for? Please elucidate me? I shan't be able to sleep until I find out, well I may doze but that not really sleep.



What IS it for? It may be something natty that I haven't considered that I need but need anyways.
