If you’ve ever had to pick up the nails littering the ground after tearing off an old roof or had to snag the bits of metal that can accumulate on a job site, this magic, er, magnetic broom is for you.
As shown in the accompanying drawing:
I created the magnetic broom by first modifying an old, defunct push broom by affixing a 1x3 to the broom’s head.
Then, I attached 10 1-inch diameter rare-earth magnets to the 1x3. (I bought mine from Lee Valley Tools.) These magnets are astonishingly strong; each one can lift a 30-lb. block of steel.
The magnets fit into steel cups (also available from Lee Valley) that are screwed to the 1x3.
— Mike Nathan, Hailey, Idaho
Safety Note: Individuals with pacemakers or internal medical devices should not handle strong rare-earth magnets.
Also, rare-earth magnets can pinch forcefully if they come together against the skin. People should always wear gloves and eye protection when handling strong rare-earth magnets.
