I can say that we do use them on EVERY Jet engine that I have seen in
the past 27 years of being a A&P mechanic. Not only in the engine oil
supply, but also in the transmission oil supply, starter oil supply,
etc... We service them about every six months on commercial Airlines.
Send an oil sample to a Laboratory, and scrap off any accumulation on
the "chip detector" plug and see how "dirty" it was. They send us back a
report of the actual percentage of metal content suspended in the oil.
High Stainless Steel content, bearings are wearing fast, etc...  So.. if
you want to know what is actually wearing inside the engine, have a Lab
do an oil analysis.

On their effectiveness on "removing nasy metal bits" in your oil, I
would not count on it, isn't that what the filter is for anyway.

P.S.

On piston powered aircraft, we always cut open the oil filter and take a
look at the stuff caught in the element.

P.S.S

And it is damn hard to find "Aluminum magnets" anyway. ;-)
