Electric magnet from trailer brakes removing iron.

Left over magnet from my trailer project, now put into service removing iron from incinerated interrogated circuit chips before refining.

Electric magnet is 12 volts DC, run off my battery charger, would work for separating iron screws from those made of stainless or brass.

The nifty thing is once the power is cut the magnet releases anything in it's grasp instantly. I have three of these magnets, later on I'm going to affix them to a long board with a handle.

might be good for cleaning up too!

I could see something like that working to clean up the garage floor, kinda like an electric broom.

2 or 3 of those mounted on a 2x4 would make a sweet magnetic broom.I have dozens of good wheelchair batteries that could power them. I guess I will have to keep my eyes out for junk trailers with electric brakes from now on. I have been using magnets knocked off the back of 6X9 car speakers but its a PITA to scrape all the iron dust off of them.

I've been using a sheet of aluminum and a strong magnet. This seems like a better idea. I'll have to hunt down some trailer magnets.
