Magnetic Drain Plugs?

Is it a magnetic plug?
Magnetic plugs are for systems without oil filters. 
No, I ditched my magnetic plug(s) in favor of the Fumoto. Magnets on the oil filter are more efficient than on the drain plug if one wants to trap ferrous material.

Great point.
Regarding transmissions, every automatic and manual transmission
I've had had a magnet built-in. You just can't access and inspect it, so
a magnetic drain plug still makes sense. It'll still catch enough ferrous
debris to compare on every OC.
Regarding Gold Plug, Dimple, ECS etc. I'm missing exact data provided.
When I make my own and by the magnets I do know what the magnets
are made drom, what temperature they're rated, how strong the are and
what glue I'm using. Too many unknowns for my taste when buying the
aforementioned ones.

Fortunately I'm wasting my own time, not yours. That said, I'm under
the impression you didn't even read this discussion before posting.

If I can find one with a built-in gasket like Ford OEM, I'd buy it. Couldn't hurt anything.
Several do, or at least did. I cannot remember which ones exactly from my past but IIRC I believe some of my VW, SAAB and BMW's from the very late 80's through early 2000's had them as OE and as 930 noted, many if not most gearboxes have them.
Should I buy the Nissan (Nismo) OEM mag. engine oil drain plug for $17+tax OR is there another brand that will supersede with a much stronger and overall better magnetic drain plug?
I bought a Votex, which is made in Wisconsin and of very high quality.

Yes, I bought the Votex as well, two in fact. Especially in aluminium gear casings it's highly desirable that the magnet stays in place, so quality counts. In an engine a loose magnet will quickly find a harmless ferrous surface. In a gearbox, well, I don't even want to think about it ...
Some cheaper magnetic plugs are aluminium with glued magnets and I'd be concerned about the differential thermal expansion cycling the glue when used in an engine. Ideally the magnet should be lightly crimped in place in a mild steel plug, generally the choice of OEM.

who makes oil filters that are magnetic?
Magnetic plugs are for systems without oil filters.
FilterMag sir! I have one and there is always an imprint....
I use the magnetic plug on my transmission on the 2005 Civic. It has no transmission filter to change. The drain plug always has some debris on it. I change out 3 liters of ATF every other year. Seems to have worked for me. I don't have one on the oil. I installed a Fumoto on my 2021 Kia K5. There is no ATF drain bolt on the K5.
I bought one years ago. Didn't know the current price....Crazy times!
I'm more inclined to put one in a transmission than an engine.
Pointless snake oil type device. There is no empirical data to support that they do anything.
The only positive thing I've ever heard is "they don't hurt".
Whoopee!!!

Do they make a significant difference? Probably not, and let's remember that manufacturers really only care about vehicles lasting through warranty.
I think they aren't a bad idea for systems without filters such as a gear case, splash lubed small engine, or differential. If we are being honest though, finding a loaded up magnet when we pull the drain plug probably means we have bigger issues anyway.
