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.

Elucidate yourself young man! Really!

I'm surprised Bonz, I thought you would have been familiar with the practice of magnetic flow control of air currents? The magnet is intended to centralise the major pressure cortex and avoid undue wear on the sides of the pipe - there is some argument about it's value but, the general agreement, is that it's worthwhile given the minimal cost overhead.

If it wasn't a magnet, it would fall off the metal ????

The magnet is only useful for cars with steel wheels. You use the magnet to stick the pressure gauge to the rim so you have it close at hand when you need to check the tyre pressure.

It isn't any good with alloy rims, because obviously magnets don't stick to alloy.
