How to Magnetize a Screwdriver to Prevent Lost Screws

Updated on August 1, 2013

A magnetized screwdriver can result very convenient in the event of trying to screw tiny screws into small electronic devices. A magnetized screwdriver may also be of great help when picking up screws with its magnetized tip.

Electronic devices, including cell phones, hard drives, lap tops, speakers, etc., all have very small screws within, which could be handled with ease with the aid of a magnetized screwdriver.

A magnetized screwdriver can help you hold small screws without having to pick them up again and again. screwing your bolts at the first try will save you lots of time during the development of your projects.

Things Needed to Magnetize a Screwdriver

  • Small magnet
  • A screwdriver
  • A nut
  • A screw
  • Staples
  • A flat working table

The objective of this project is to magnetize one screwdriver; however, you can magnetize as many as needed.

Those of you who like to work on mechanical artifacts, such as electronic devices, appliances and cars, that include screws and bolts in their design, sometimes have been faced with a situation where a bolt, nut or screw has slither deep inside the artifact they´re working on. To get that small metal thing out from its hidden place, requires lots of artifices, but rarely one will help get that thing out, and the project, most of the time, has to be delayed.

There is no need to worry about not having a magnetic screwdriver, like the one a mechanic uses, to come to a solution to this inconvenience. The most effective way to obtain the magnetic effect, without having to buy one at the store, is to magnetize your own screwdriver.

Technique to Magnetize a Screwdriver

Grab your screwdriver by the handle with your left hand; hold the piece of magnet with your right hand; move the magnet along the tip of the screwdriver in one direction ten times. The screwdriver should have picked up enough magnetism. Test the screwdriver by putting the tip of it on the head of a screw or nut. If the screwdriver is able to uplift the screw or nut, it has been magnetized.

If it hasn´t, slide the magnet along the screwdriver one more time. Remember to move the magnet gently along the tip of the screwdriver in just one direction.

How to Demagnetize a Screwdriver?

To demagnetize the screwdriver, you just need the reverse the procedure. Pass the magnet over the screwdriver´s tip in the opposite direction from the one you rubbed it while magnetizing it. Moving the magnet over the tip of the screwdriver about three times will suffice in demagnetizing its tip. If you´re not able to demagnetize it at the first try, try it once more.

  • People in ancient times learned about magnetism from lodestones.
  • The word magnet in Greek means stone from Magnesia (region where lodestones where naturally found).
  • Lodestones were used in navigation in the 12th and 13th centuries, as they function as natural compasses.
  • Magnets were known by the Greek, Indian and Chinese civilizations 2,500 years ago.
  • The first written description of magnets was written by Pliny the Elder in, ¨Naturalis Historia.¨

What Produces Magnetism?

Ferromagnetic materials are those that show magnetic properties or those that are attracted to a magnet, such as most metals, including cobalt, nickel and iron. These materials can be magnetized, so that they can become magnets.

An unmagnetized object, such as iron, consists of magnetic molecules that are randomly aligned. For magnetization to occur, those molecules have to align with the magnetic field applied to it. When the molecules in iron get aligned with the magnetic field at which they´re exposed, they align with that magnetic field, creating their own magnetic field.
