That's encouraging insight, Paul; the fact that there is rust "dust" and rust "chunks". The rust "dust" along with regular dirt is probably fine enough to pass through the mesh at the outlet and get picked up by the fuel filter. It's the "chunks" that cause the problem of clogging....and perhaps they indeed have enough original base metal that they would get grabbed and held by the exterior magnets.
Well....I just happen to have a stack of magnets laying around....so I will attach them, and then wait 30 years to see the results!! And yes, I always try to keep my gas tank full to minimize air/water vapor. Also, when I replaced my fuel tank I made sure I got one with a 12 mm outlet as opposed to the original 7 mm outlet (almost triple the cross-sectional area). So kind of a multi-pronged approach at solving this problem.

I think ethenol needs to be added to the rust adding conservation. Alcohol absorbs water. This is likely only a problem if you are not burning fuel quickly enough (storage). Here in northern MN it is difficult to source any gasoline that does not contain some ethenol.
Making sure your tank is full can reduce chances of condensation in the tank during storage. Moist air will condensate on the coldest surface, let's hope that is not the inside of our cold metal gas tanks.
And yes, most rust of any color has enough "original" material that a strong magnet will attract it quite readily. I have enough rust around the drive way (again, northern MN) that I tried with computer magnet...

So David is basically right. Not sure which rust forms in our fuel tanks; pictures I've seen of clogged fuel filters and cut open fuel tanks show mostly red rust.
So the magnet idea might not work. Oh well.

Yep, it sure is; that red rust and all; it's Iron, just like those magnificent hills in the Southwest USA.
OK...need somebody to go out to get some red dirt....with a magnet....and see if anything collects. I'm sure it will happen.

I don't believe ordinary red rust is magnetic...
