How To Magnetize and Demagnetize a Screwdriver

Ever experienced having a hard time using a screwdriver because the screws kept on dropping and falling off before you’ve screwed it on adequately? Here’s a quick and easy solution: why not magnetize your screwdriver, so that the screws would stick to the screwdriver and won’t fall off?  The great news is that you could easily magnetize your screwdriver for this purpose. Here are the steps to follow:

  1. Prepare the materials. All you need for this project is your screwdriver, and a magnet. For best results, use a magnet with ¼ to 1 pound strength. Also, it’s a good idea to gather all the screwdrivers that you’d want to magnetize, so you can magnetize them all in one sitting.
  2. Begin magnetizing. Slide the magnet lengthwise from the base of the screwdriver blade (the part near the handle) to its tip. Remember, the sliding motion should be one direction only: don’t run the magnet back and forth across the blade. So again, slide the magnet from the base to the tip, for about six times. Also, don’t stop once you get to the tip; slide the magnet smoothly right off the end. Now you have a magnetized screwdriver!
  3. Just a few more things to remember. Don’t use a very strong magnet to magnetize your screwdriver, since you’d only be working with small to medium-sized iron screws. Plus, having a screwdriver with too-strong pickup might likely be an annoyance more than a help. Also, do not place your magnetized screwdriver (or any other magnet) near your computer or its components, since this could mess up some internal parts.

Using magnetized screwdrivers is great if you’re working with wood, but what if you’re using your screwdriver with steel parts? That’s where you have to know how to demagnetize your screwdriver. This is really easy too:

  1. Get your magnetized screwdriver and drop it about two to three times. Do be very careful not to break the blade; dropping it about two feet from the ground should be adequate. Dropping the screwdriver will cause vibrations that will break the magnetic alignment, and would therefore cause demagnetization. That’s why if you’re not yet planning to demagnetize your screwdriver, you’d have to be careful not to drop it too much.
  2. Another option for you to try is to run the magnet the reverse of what you did to magnetize the screwdriver; that is, slide the magnet from the tip to the base for about six times.

There you have it! Magnetizing and demagnetizing screwdrivers is really a very easy project, which you could do in under five minutes. Do know that you could also magnetize your screwdriver by attaching it to a large, 6 volt, dry cell battery and using copper wires and wire strippers, to produce a more highly-magnetized screwdriver. However, the process described above is much, much more simpler and should be adequate for the basic screwdriving needs. Good luck!
