Yes, they have been around forever.  Race cars almost always use a magnetic plug because if there is any steel flowing around in the oil we want to see it. A magnetic plug will usually catch some of that and it can be readily observed when the plug is removed for an oil change.

Is it necessary?  No.   Is it nice to have?  The better question is:  Do you care?

I agree with Richard with respect to engine drain plugs although I always
install them myself.
The same is not the case with gearboxes. Because of the abuse meted out to
the unsyncronized 1st and reverse gears in Healey boxes chips of hardened
steel frequently circulate within the gearbox oil and invariably eventually
find their way into the laygear needle roller bearings upon which they
wreak havoc. The overdrive units originally featured magnets at the drain
plug but even if these are in place, as they frequently aren't,  they don't
seem to gather up all those chips quickly enough.
Installing a rare earth magnet on the gearbox drain plug is a very
worthwhile exercise.

OK, thanks one an all. Do you know if the original and the magnetic are the
same spanner size ie across the flats?

There are also magnetic jackets that go around the exterior of engine
canister (spin-on) oil filters though you would not be able to
determine what if anything *additional *was collected by the magnet.
In any case I generally cut apart my oil filters and examine the filter
media for shiny bits of bearing surfaces.
