Wouldn't the filter trap any metal particles?

I would think that, if it's such an improvement, it would be a standard thing on all cars.

i'm not a fan of anything magnetic being introduced to the oil system. if you magnetize particles, they can stick to thing you don't want them to (like your crankshaft). those things, and magnetic drain plugs, aren't fool proof. they can't hold onto everything. stuff gets loose. that's when the problems begin.

If you're "making metal" (in this case iron) to the point that significant amounts are picked up by a magnet, you have a definite serious problem. Just removing some of the particles by a magnet is not going to solve the problem or protect the motor from further damage. What this can do, though, is alert you to the fact there is a problem. However, the only way it can do this is if you cut open the oil filter and see these particles. How many of you do this?

On piston aircraft engines it's proper practice to cut open the oil filter, cut the paper element off the core, pull it apart and inspect. I've adopted this practice with the Canton filter on my 968 and do cut open the replaceable element and inspect the paper filter medium every oil change.

This practice is a good early warning system and worth doing. Much more helpful than a magnetic device.

We had an Oberg on the race car, and we checked it with a magnet after every race. It's important to remember that there are metals in the engine that are not ferrous and you need to know if they are in the oil as well. We routinely found iron and steel, lots of brass and bronze alloys, as well as the odd bits of plastic and gasket materials. Inspecting the filter is crucial for an engine that is run hard, in my opinion.
