Expensive screwdrivers are usually already magnetised. The purpose of this is to make it easier to screw in hard-to-reach places. But what do I do if my screwdriver is very old or simply not of high quality? Or it is simply far too weakly magnetised. There are 2 different ways to magnetise it with magnets:
Possibility 1:
Screwdrivers that have never been magnetised can be made magnetic using this technique. For this we need a strong magnet. We have used the neodymium
square magnet 50 mm x 20 mm x 10 mm here. Of course, you can also use other magnets. It is important that the magnet is made of neodymium and is at least approximately the same size as the magnet used. Otherwise, the screwdriver will simply be too weakly magnetic and only very small screws can be held, or the screws will fall off very quickly with smaller impacts.
To magnetise the screwdriver, first protect the very strong magnet with a thin cloth or a piece of thin cardboard. Then carefully place the screwdriver on the protected magnet. Then pull the screwdriver away to the cross/slotted side over the magnet. Repeat this several times. It is important that you always pull the magnet and screwdriver in the same direction. This aligns the elementary magnets in the screwdriver to the same side
Your screwdriver should now be magnetic.
Option 2:
You can also make a screwdriver magnetic by attaching a strong neodymium magnet to the screwdriver. In our case, we used the
ring magnet Ø 10.0 x 4.0 x 5.0 mm.
As long as the magnet remains on the screwdriver, it is magnetic. This means you can even attach screws overhead without having to hold them with your second hand.
You can also use block magnets or neodymium disc magnets for this application instead of neodymium ring magnets. However, it is always important that you leave the magnet attached to the screwdriver as long as it is to remain magnetic.
