Oil Filter Magnets
Certainly not my idea...saw them advertised in an Auto Mag somewhere.
I purchased four small magnets, 1/4 inch thick, 3 inches long and 3/4 inches wide. I place these magnets on the side of my oil filter. I have been doing this for about six months. I have never lost a magnet.
On my first oil change, I cut open the filter and found 4 areas of grey "sludge" on the side of the filter about the size of the magnets. I believe the magnets are removing ultra fine particles of metal from the oil.
You can buy "aftermarket" magnets for about $50.00 or do as I have done for less than $5.00. Mine actually cost much less as I purchased them in Hong Kong but I have seen them at Harbor Freight for about $1.00 each.

Flexible Magnets?
I am not really sure what you are talking when you mention Flexible Magnets. I imagine any magnet would work. As I said the ones I use are just 1/4 X 3/4 X 3 inches and I happened to have four of them, so I used all four. I imagine just one magnet would do the job.

Have an old disc drive? Take it apart (good practice anyway) and remove the two magnets inside (one on each side of the disc). These are incredibly strong. Stick it to the side of the filter, it sure won't fall off and will attract any metal particles that comes within its field.

That's a great idea. I bought drainplugs with magnets for the engine, manual trans, and diff. Same idea - when you drain the oil you'll see the end of the drainplug has a kind of a metal sludge stuck to it.

These are the same kind of magnets used in disc drives.

Anyone interested in going in on some of these? The quarter sized ones would work perfect.

This is a common trick after rebuilding a motor so new shavings from brake-in stay in the filter. you can tape a magnet to it as well so it wont fall off. its cheaper than a new crank and bearings

and for $20 you could outfit several cars
that's a good deal, i might just order those!
i went ahead and ordered them - it was like $7.50 to ship so not a bad deal altogether!
thanks torchredfrc for the link! now both my vettes will get "protection"
***EDIT*** FYI - none of those are quarter size - they appear to be the size of watch batteries - heres the pic from their gallery

I've got the magnetic tipped oil drain plug.... bought from the local Chey dealer for around $4 - $5
I just changed the oil last week and there were some small metal particals and sludge on the end.
A good investment.

Oops, I noticed they were smaller than the quarter after I posted. I was referring to the ones on the far right in the picture. I don't know if I would feel comfortable putting one of these inside the drain pan (on the end of the plug). To me, that is just asking for trouble... I would hate for the thing to come off in the oil & that would be just my luck.
