Anyone who has taken apart a small device knows the pain of constantly dropping and losing the tiny screws that hold everything together. A simple solution to this annoying dilemma is a magnetic screwdriver, which you can easily make at home! All you need is a screwdriver, a neodymium (or other rare earth) magnet and a few spare minutes.
Purchase a strong rare earth magnet from a hardware store or online retailer, and run it along the edge of a screwdriver.
Repeat the motion, going in the same direction each time, and slowly spin the handle to magnetize the entire tool.
The more passes, the stronger the effect! Use your magnetized screwdriver to avoid dropping screws and to pick up loose ones.
