Exactly what do they do, and how do they do it....I saw these cleaning magnets at the lfs...and couldn't for the life of me figure out how they clean the tank.

they work well enough on soft algae...one side goes in the tank against the glass...the opposite pole goes on the outside of the tank...the magnetic field makes them clamp together...they have algae scrubber material attached and you just move them around to scrape off the algae.

They are about as effective as a rough sponge scrubber...you just don't have to get wet using it! ;) They don't work so well on hard algae though.
