I have an interesting experiment I may try; mixing two different magnets in a P90. The P90, for those who don't already know, has two bar magnets inside that cover. My experiment, unless someone has a logical reason or reasons to turn me around on this, is to use one ceramic and one Alnico magnet. As I've been told, they should be close in Gauss measurement, or the stronger one will demagnetize the weaker one, so I would most likely use an Alnico 8 magnet.

Has anyone here ever tried this, and if so, what were the results?
