Magnetising a screw driver

Screwing something on horizontally/vertically? No problem with a magnetised screw driver!
Author: Dr. Matthew Yong, Cambridge, United Kingdom
Good screwdrivers should be magnetised these days, which would make it easier to get screws into harder to reach places. Magnetisation also comes in handy when you need to pick up a screw from the floor. Unfortunately, my screwdriver is pretty old and weakly magnetised: He barely manages to pick up a screw.
As soon as you shake the screwdriver a little bit, the screw falls off. I decided to breathe some life into my screwdriver. I only had to put a ring magnet on the screwdriver, which makes the screwdriver itself magnetic.
Now, the screwdriver can hold up to five screws at once! If you have only one screw at the tip, it sticks pretty well to the screwdriver and you can even screw it in headfirst.
It's important to keep the ring magnet on the screwdriver - if you take it off, the screwdriver loses its magnetisation right away!
It also works with a screwdriver that hasn't been magnetised before. As you can see, it doesn't attract any screws at first.
You can protect a large block magnet with a piece of cardboard (important!) and place the screwdriver on the cardboard. This way, the molecular magnets in the screwdriver align equally.
The test proves: Now even this small screwdriver holds two screws at once!
Note: Screwdrivers lose their magnetisation relatively quickly again, but a super magnet magnetises them again in a few seconds.
Additional comment from our customer Joris: If you need to screw in a screw into the ceiling headfirst, you can attach it to the screwdriver with two S-15-03-N disc magnets.
