Not sure about filter magnets, stuff that passed through modern filters must be tiny.
Would make an interesting experiment.

Well, I think you're more holding the crap to the wall of the filter so it doesn't clog the filter element. I think either way the amount of metal cars shed isn't much, we just do it because it makes us feel better.
And $2-60 investment on $30-50k isn't much
