Cool read. They refer to a graph or graphs that I did not see. Do you know where it is (they are)?

Interesting read, " use and clean your magnets" (before they load up) message is interesting.

Well - yeah pretty much every time I change the fluids the mags get cleaned and checked so ok there......

Continues ongoing debate about placement with a low slow recommendation (drain plug / pan mag ) vs a filter or direct flow.

Thanks for posting !

I'm surprised they did not mention anything about possibility of escaped particles from the magnet (particles which are now magnetized) sticking to the moving parts and causing more accelerated wear.

Thats only an issue in a cold system.

Temporarily magnetized particles lose their magnetism extremely quickly with any heat.

Try it - magnetize a pin and then warm it with any heat source and watch the magnetism vanish.

Uncle, the particles would need to reach the curie temperature for the material, and I doubt that could be reached in oil by any material.

Aside, when in middle school, I made a "Tesla's Thermomagnetic Motor" using that principle.

They did not mention that the particles were magnetic but they did intimate that at first the magnet collected coarse sized particles and then with continued use (and those coarse particles NOT being cleaned off) the magnet collected ever finer particles. Implication is that the coarse particles were swept off with the fluid currents, again making their way to the rolling element bearings and the gear contact faces and then being ground up to finer sizes (but in the grinding action - taking their toll on bearing and gear(face) life expectancy). What this also says is that if you don't equip your machinery with magnets RIGHT FROM THE OUTSET OF OPERATION (and remove, clean really often at the first stages of break-in) - then you're sunk right from the get-go.

I read about that years ago, posted about it here and caught a lot of flack. Either way it was an interesting debate.

If there was no magnet, ALL those particles would be circulating around...so catching whatever you catch is better than catching nothing at all.
