Unlike a piston engine there are no moving parts near the oil pan. Epoxying a magnet to the drain plug will hurt nothing. If it falls off, it will merely stick to the oil pan at a point near the drain plug.

The idea behind a magnetic drain plug is to catch the microscopic metallic particles that are the result of normal engine or transmission wear.
The magnetic plug is much more critical in a transmission than the engine in my humble opinion. The tranny has no filter system and all (except for the synchros) of the material that is subject to wear is ferrous. It makes sense to try to capture as much of this as possible with a magnet.
The engine, on the other hand, is a different story. There are virtually no ferrous metal parts to wear that are in contact with the oil. The apex and side seals do not have any way for their wear particles to enter the oil system. They simply expell their microscopic particles out the exhaust port. This is the same escape route that blow by takes. It is the reason that rotaries do not turn the oil black with mileage the way recips do.
Still it can't hurt anything. I feel that if Mazda thought one was beneficial they would have installed it from the factory as the tranny has. As I said, there is very little in the engine to trap with a magnet.

Former Moderator. RIP Icemark.
There was a strap thing a couple years back that wrapped magnets around the oil filter, for the same reason.
I would think Zip tying a good size neomidum magnet to the side of the oil filter would work as well.
