Magnetic sump plugs - do folk here use them?

I guess it's a spill over from my old Mini days as BL always fitted magnetic sump plugs to the transverse A series engines.
I have them fitted in our Merc & Jeep.

Are they worth having on a bike to help with keeping an eye on engine & gearbox wear?

I know much more complex methods are used in large industrial engines such as in Cruise Liners where oil analysis "Cartridges" are changed during servicing with oil analysis being used to ascertain the amount of engine wear from the metals found in the used oil & cartridges.

My Z thou and my Honda 4 have them and i never put them in, you may already have one in it.

Bryanj:
You never change the oil in a cruise liner just constantly centrifuge it to remove contaminants, test yes and change on rebuild but there is several TONES of oil in ther

fogrider:
If I remember rightly, when the Mini came out, the fact the gears were in the same sump oil as the engine, BMC thought  it a wise precaution to capture swarf off the gearset as it bedded in.
As most Japanese bikes have common gearboxes too, I consider it essential. There are some fierce , tiny, bar type magnets ( about 20mm by 6mm) that fit easily in a sump plug.

Essential item !

Interesting I never knew that about Ships engines but it makes sense. Interesting that Honda used a type of centrifuge on the old 250 Dream instead of a filter cartridge.

My friend was in the field of industrial oil analysis to analyse engine wear on industrial engines - not sure if his customer base was in shipping, aviation, automotive  or large static engines in power generation as I only see him ever few years as he moved to Conwy decades ago.

The founder of the company link below  is Robert Cutler he recently retired only to open his own company 6 months later in the oil analysis field with his son Mark. He was my best man back in 1978. I told him he was mad starting up a business when he was 70 yrs of age but he tells me that business is good!
