Well......written by Jim Smart.
Seems to be a sales write up.  I admit to only browsing the write up, but I don't see any "Hard Data" (Charleston Heston, since True Lies was on the TV last night). 
I've never used one.  I put 200,000 on a F250 7.3, only doing oil changes every 3,000 miles, including filter.  It ran great.  My Mustangs all went over 100,000 with no issue and internal bearings looked fine on tear down. 
But I'm open to the idea.

I am intrigued by the idea. It might end up being only a placebo but what if it isn't?

Dont think it is a placebo, have a friend of ours that has a dedicated track car. He has had one on there forever,  sends his oil to get tested religiously and opens up his filters.  Finds small particles stuck to the filter / can

if you have magnetic particles in your engine oil a magnet  is not going to fix the problem .

Magnets will mostly attract some sludge. Some factory automatics come with one in the pan. I have some in my heads incase anything brakes. You can also buy some really strong ones that you can just stick on the outside of your oil pan also. I do have a couple that go around the filter, can't hurt.

What are pistons and bearings made out of ? will pieces of them stick to a magnet ? If you have pieces of metal in your oil filter that will stick to a magnet you have some major wear problems that most likely will notify you by being noisy. Waste time and money.

Anything one can do to trap particles is good, if it's a magnet well it's a magnet

Maybe so but it seems to me that screens epoxied into place in the oil drain back holes in the heads is now very commonplace on heads.

I had only once a set of push rods loose the tips and wind up in the oil pan on a Boss 351. They shattered pretty extensively and a magnet on the oil filter was cheap insurance in my mind.

Sometimes mental health is the issue at stake?

Yep.  And it seems to take about 3 paper towels to get that sticky sludge off.   I've also found that some drain bolts are magnetic.  I've changed the CVT fluid on the wife's Honda and the end of it inside the transmission, looks like your finger tip.  Rounded end.  It attracts the sludge.

Maybe the sludge has microscopic metal particles in it

The sludge is metallic powder mixed with water. It becomes a solution.

magnetic metal in  transmissions is normal/  magnetic metal in engine oil pan is very rare / and usually means  you have a  problem . magnet isnt gonna fix it

Doug so in theory " the magnet " maybe a good thing
