Real Dirt and Magnetic Particles

[doctorwayne]

Kevin, the thing about a permanent magnet is that it is difficult to get the little magnetic bits off the magnet when you want to clean it up. And then the bits tend to get knocked off back into the dirt when trying to suck them out of the mix. A big electromagnet would be perfect.

If you use a permanent magnet, put it in an oversize clear plastic bag, then, after you've passed it over the area to be cleaned, evert the bag to encapsulate the particles.
