I purchase small "rear earth" magnets then use JB Weld to glue them into a
shallow recess drilled into the inner surface of the drain plug.
Works great and even if the glue were to let go the magnet would stick to
the case and still do its job.

Where does one get a magnetic plug for our gear boxes? Usual suppliers?
