Why Do Screwdrivers Become Magnetic?

Why Do Screwdrivers Become Magnetic?

Before getting into further details, let’s briefly discuss screwdrivers and why screwdrivers become magnetic. A screwdriver is a hand-operated tool, commonly used for turning screws with slotted heads. Multiple types of screws exist and adversely, multiple types of screwdrivers exist to deal with those screws. Standard screwdrivers come with flat blade tips available in a variety of sizes, while special screwdrivers offer a slot-shaped head with a blade tip that fits the slots.

The main screwdriver shank is built with tough steel and the other tip is hardened enough to minimize the wearing part. The handle body is generally made with metal, wood, or plastic. You can either use it by hand for basic screws fixing or attach it to an automatic handle that rotates when you push the screw head through a power drill.

Do you remember the feeling when your screwdriver was not long enough to reach the screw and it was slipping down? Yet the hassle was saved as the screwdriver became magnetic and got stuck with it? Yep, we are talking about that! Screwdrivers become magnetic, but ever wondered, why do they become magnetic? Further, check out the Best Screwdrivers for HVAC Technicians in 2021 right here at

Why Do Screwdrivers become Magnetic? Let’s dig in further!

Before digging into the whys and how’s, let’s talk about why it actually happens. There is a scientific concept known as the magnetic moment. A magnetic moment is a typical activity of any object that allows it to get attached to a magnetic field. Every steel object contains a set of electrons, i.e. screwdrivers when those electrons are exposed to any magnetic field, they become aligned and parallel to that magnetic field’s lines surrounding them. Do you know what company makes the best screwdrivers?

And that’s how your screwdrivers become magnetic! The top benefit of a magnetized screwdriver is that it does a great job of holding onto a screw, especially at the start of any screwing action, if the screw is small. So if you are worried that your screw will fall on, you can get it magnetized and you are good to go! Find out about the best quality screwdrivers?

How to Magnetize a Screwdriver?

It’s quite frustrating when you are constantly trying to fix a screw into a tight corner, but it keeps on falling to the ground and you have to start over every time. Well, the good part is, the solution to this problem has been found! Save yourself some time by turning your screwdriver into a magnetic one. Here are those few steps. Also, see what are the best insulated screwdrivers?

Look out for a magnet.

First, you need to search through your toolbox and find yourself a strong magnet bar, the stronger it is, and the stronger the magnet will be. You can find a rare-earth magnet or a neodymium magnet of at least ¼ pound. If you are unable to find one long bar, get two of them that make up for them the same quantity.

Don’t forget to clean the screwdrivers.

Before starting off with the project, remove any dust or grime from the screwdriver that might disrupt the magnetization. You can surely use a damp towel to clean it properly, however, don’t forget to dry it afterward.

Rub the magnet onto the screwdriver surface till the top.

Choose an end of the magnet and touch it down to the surface of the screwdriver, all the way to the tip. Drag it up and down for a few minutes, this process will cause small magnetic domains and regions within the steel to align in the direction of the magnetic field. Make sure you are doing it upwards and not downwards.

Repeat the process in the same direction.

Once you are done with the above process, take the screwdriver off the magnet and drag down from handle to the tip again in the same direction while using the same end of magnet each time, repeat the same process several times. Do not break the loop by moving the magnet in both directions, this will undo the entire process.

Keep on turning and rotating the screwdriver by a quarter turn, drag down the magnet from handle to top tip multiple times.

Time to test the screwdriver!

Try to pick up any screw while using the tip of your screwdriver and keep on repeating the process. Try doing it at least 10 to 15 times, if it still doesn’t work out, try the whole process with a stronger magnet or a magnet with more quantity of neodymium. If you are using a Phillips – a hard screwdriver, then it must remain magnetized for several months. Also, search about the types of screwdrivers?

Once you successfully magnetize it and the purpose is fulfilled, you can easily demagnetize the screwdriver by whacking it against the wall to scramble down the magnetic region or simply run the magnet back to the other way around, tip to the handle.

Multiple types of magnetic screwdriver bits!

If you ever sit down and try calculating how many types of screws are there, you will get an idea of how many different varieties of magnetic screwdrivers are needed to match with the screws. If you ever look up a screwdriver catalog, you will find that the screwdriver bit contains 20 pieces, 50 pieces, 100 pieces, and even more than that!

Wrapping up the things!

We know how frustrating it can be when you are trying to get the screw fixed yet it just won’t fit, to make things easier, a simple science of screwdriver magnetization came into place. Now that you know why it happens and how it happens, you can surely try it out for yourself. Also, keep on learning further about tools and how long do screwdrivers last?

There are multiple types of screwdrivers that exist, such as Flathead, Phillips Screwdriver, Star Screwdriver, Hex Screwdriver, Pozidriv Screwdriver, Tri-Wing, and much more. Every screwdriver can be turned into a magnetic one if you know the right technique. So, it’s high time to try it out now!
