You can buy aftermarket drain plugs with magnets that attract said metals. As far as the filter is concerned I would be hesitant to clog parts of the filter you do not want to clog for flow aspects. But I have not torn one apart to see just how they filter nor am I even sure you would collect enough metal to even do such a thing. I think you are reaching for a fix to something that is not broken. Attach magnetic drain plug, change oil when needed...or sooner if it makes you happy. Done.

You won't need to wipe anything off because the particles will be inside the used oil filter that you are taking off and throwing it away.
Then you just place the magnets on the new oil filter and the cycle starts all over again. You just move the magnets, no wiping anything, except to clean road gunk from the magnets before you place them on the new filter.

The 2.7/3.0 EcoBoost uses a plastic housing to contain the filter cartridge. So there's no metal shell. No metal oil pan, No metal drain plug. I'm in the same boat as I'd like to have an oil filter magnet or oil magnet to pull fine metallic particles that don't get trapped by the oil filter.

This is probably the best method for the 2.7L. Epoxy several rare earth magnets around the perimeter of the plastic canister.

If that's workable, you wouldn't need to wipe off anything. You'd be changing the filter. The metal is caught in the filter. Just change the oil often and I do mean often.

No, using a magnet anywhere in the system will have zero effect. The ONLY possible place it makes sense is the drain plug. If not there by OEM, it doesn't need to be there.
Period.

Once a quantity of ferrite shavings accumulate in magnet what happens if a clump is shaken off? Vibrating on a magnet will get magnetized. Do you want those circulating in your engine? If they are big enough they will be trapped in the filter without need of magnet. Perhaps someone would be gracious enough to run a magnet over their filter next oil change?

Would have been trivially easy for Ford to include a magnet in the crankcase or oil filter but for some reason they did not. Mercedes-Benz did not, Yamaha did not, and Subaru did not. Am guessing they know something and are not just being cheap.
