Magnet / Tool for picking up nails, staples, etc. from soil

[(unknown)]

I need to clean up around my house after replacing the cedar siding, sheathing, wrap, etc. Lots of nails, staples, etc.

Does it even make sense to think of using some kind of magnet for this task?

If so, what sort of magnet would work? A switchable electromagnet makes some sense.

I'm new to this board (in case that matters).

Sure, I do it all the time.

Slip a good strong magnet into a heavy cloth or plastic bag. drag the bag around as you walk the area. After you are done turn the bag inside out pull the magnet free and you have a bag of ferrous metal debris neatly contained in the bag. Don't use the magnet bare to do this or it may take a lifetime to pick the stuff off of it, especially the little bits.

Problem being many roofing fasteners are aluminum and magnets do not pull aluminum to them.

Use the magnet from an old junked speaker, these are readily available at the local convenience center or junk yard.

The clutch coil from an auto air conditioner makes a great 12 volt pick up coil.

Use a battery to energize it, disconnect the 12 volts and everything falls off.

No picking pieces off the magnet.
