Magnetic oil plug bolt?

[Fintail Fan]

I haven't yet changed the oil myself on our 1992 300TE 4Matic Wagon, but am planning to do so soon now that I have the OEM filter and a level place to do it. I was wondering though if the lower oil plug is magnetized to catch small metallic particles as they settle in the oil pan. I used to have a Toyota that had a magnet on all the lower plugs and at every change there was always an amount of small metal particles covering it. I'd hate to think that metal particles, even that small size, are being re-introduced to the engine. Also, if it is not magnetized, would it be safe to epoxy a small round magnet, (type used to hold cabinet doors closed), to the end of the plug for this purpose? Same question for the transmission fluid. Thanks.
