Relevant part of the aforementioned article.
"Recently, magnetic filter additions have started to surface. I was sent one last year to try out and it really did seem to work. The product in question was called the Bear Trap BT500. Their website can be found here. It's basically a sleeve made of foam rubber and plastic with some magnets in it. It bends to clamp around the outside of your regular spin-on oil filter.
The idea is that the magnets will attract any metal debris in your oil and stick them to the inside of the oil filter wall, thus preventing them from going back into the oil circulation. Being of a curious nature (or stupid, depending on how you look at it) I decided to dismantle my oil filter after using the Bear Trap for 5000 miles. I learned a couple of things.
1. You shouldn't try to do this yourself.
2. It's bloody messy.
3. But most importantly, after a brief period in accident and emergency to stitch up the gash in my hand, I discovered that sure enough, there were tiny arrangements of metal filings clustered around the inside of the oil filter wall where the magnets from the beartrap had been. You'll excuse the lack of photos to prove the point, but I had other things to worry about.
So can I recommend their product? Yes."
I think it sounds like a pretty good idea, I wonder if sticking a magnet on on the bottom or your diff/gearbox would benefit too.
By looking at the flow diagram here.
I think it would be best just to put one on the bottom as all oil passes past there anyway. And also that way, it's the further away from your block. I don't know if I really like the idea of a magnet being that close to high speed, precision, moving parts though.
