Can magnets keep oil cleaner?

From my understanding, the smaller a particle, the less attracted it will be to a magnet and the more likely that the flow will push it along. With that in mind, only large particles that would have been otherwise caught by the oil filter will be trapped by a magnet, while the smaller ones will move right past the magnet entirely. While I am confident that particles will be caught by a magnet, I do not think that any of the ones that are caught would be ones that would have otherwise avoided filtration.
Well the magnets are pretty strong, have you tested them. Im sure they can pull metal fragments that the filter cannot catch.
One question I have is that does the magnets actually damage the filter. Heres what Im thinking. The magnets are PULLING the metal through the filter...and any big pieces of metal is being pulled through the filter and there by tearing the filter.
Or am I just thinking things up?
sinsata: good point...or at least good thought process.

Well, the flow goes from the outside to inside ..so it's unlikely that a particle is going to get by the magnet and then get pulled back through the media ..or so I reason.
Yes, as Gary as stated, the oil flow is from the outside in and I have cut literally hundreds of oil filters with Neo magnets installed and certainly no damage to the filter element. The particles are pulled from the oil prior to the media. And yes, high quality Neo's pull from angstrom level to chunks and clunks, equally.. Thus greatly increasing the oil filters filtration capabilities. Caputuring the #1 wear component (iron/steel) and allowing the filter media to do its job on non ferrous better.. Basic win/win...

Very well stated sirs.
If you have very strong magnets, stay away from the top and bottom. Top could impede/block drain back device. Bottom could tip the spring over.
I think those magnets are much stronger than what's being discussed here.
Some of the rare earth magnets have 11-18 lbs of pickup power even in a penny size shape. These magnets can slam your fingers together and pinch/cut the skin. The springs in the filter hold the filter up against the top of the can/lid. If these magnets are placed close to the bottom....I believe they could pull the spring towards the magnet.
Sounds like an experiment is in the making...
is this the type of magnet you are talking about?
how many would you put on an oil filter?
what size?
round, square?

LOL! Not all neodynium magnets are created equal.
The most common ones are of low temp (room temp) varieties that as soon as it goes beyond 80~135C, it will loose most of it's magnetic power.
There is another higher temperature neo magnets available for use in oil filter applications but are very difficult to come by.
