Anyone epoxy magnets inside the engine?

I have seen drain plugs with a magnet on it

I use one of those. It just collects a type of antiseize on it.

I think more than one company makes a big ol magnet you slap onto the oil filter. All that being said I don't really know what the point is, as the metal you really care about is nonmagnetic (bearing material)

I have a magnet in the transmission pan and a magnetic drain plug in the engine oil pan.
Those can send you down a rabbit hole thinking the engine is coming apart. 
When I was doing the 5 speed Tremec swap, I had to pull the pan to pound out a dent. I found some goo on the drain plug and thought I had a crank bearing going bad. Everything checked out fine.

Just slap a high strength one right by the pan drain or on the filter for micro particles.

if you did find anything you can have the oil burned/analysed. we do that on airplanes..here;s one kit

I have wondered about S.O.A.P. samples on cars. Have you used these? Do you use a standard hours of service on the oil for a sample ?  On turbine engines we took the sample at a specified hour , not at oil change like I assume you would with a car. Do they have a baseline for BB Mopar engines?

I've never used it for a car, was never really that important. I suspect the people that burn the samples have to limits..at least I hope
