How to Demagnetize a Screwdriver?

How to Demagnetize a Screwdriver?

If you’re a professional technician, an avid DIYer, or a hobbyist, chances are you’ve been in the situation where your vital tools have become magnetized when working around metal objects. This can be especially problematic with screwdrivers, as they will start to attract small pieces of metal and other debris that can get stuck on the blade or tip.

Fortunately, it’s relatively simple to demagnetize a screwdriver with the proper tools and techniques. In this article, we will go over the basics of how to demagnetize a screwdriver safely and effectively without risking damaging or weakening its handle or tip. We’ll also answer some frequently asked questions about demagnetizing screwdrivers and provide some useful tips.

Why Use a Magnetic Screwdriver?

A magnetic screwdriver can be a useful tool for any technician, DIYer, or hobbyist. By being magnetized, the blade of the screwdriver will help hold fasteners like screws and nuts in place while you work on them. This allows for greater precision when tightening or loosening fasteners as they won’t slip off the tip of the screwdriver. [1]

Why Use a Magnetic Screwdriver?

Step 1: Materials


In order to demagnetize a screwdriver, you will need the following items:

  • A strong magnet
  • An iron core (like a nail)
  • An electric current generator (such as a battery) [3]

Step 2: Start Your Heating Element!

The first step is to create a heating element that will be used to demagnetize your screwdriver. To do this, you’ll need an iron core (like a nail) and an electric current generator (such as a battery). Wrap the iron core around the head of the screwdriver, and then attach the positive wire from the battery to one end of the core and the negative wire to the other. This will create a small amount of heat, which is necessary for demagnetizing your screwdriver. [3]

Step 3: Wait

Once your heating element is in place, you’ll need to wait a few minutes for the screwdriver to become demagnetized. After about five minutes, test the screwdriver by attempting to pick up a small steel object (like a paperclip). If it doesn’t stick, then you know that the screwdriver has been successfully demagnetized. [3]

Step 4: Temper/cool

Once you’ve successfully demagnetized your screwdriver, you’ll need to temper or cool it in order to ensure that it stays non-magnetic. To do this, place a strong magnet on either side of the head of the screwdriver and hold them firmly for about 10 seconds. This will help to even out the magnetic charge and make sure that your screwdriver stays demagnetized. [3]

What Is a Demagnetizer and How Does It Work?

Overview of Demagnetizers

A demagnetizer is a device that can be used to remove the magnetic field from objects, like screwdrivers.

It works by using an alternating magnetic field to remove any residual magnetism left on metal surfaces. This process of demagnetizing is often used on precision tools such as screwdrivers and drill bits to ensure they are not affected by magnetism when in use. [2]

What Is a Demagnetizer and How Does It Work?

How To Use a Demagnetizer

Using a demagnetizer is relatively simple. For the best results, it’s important to ensure that the object you are trying to demagnetize is completely clean and free from dirt or debris before using the demagnetizer. This helps minimize the time required to demagnetize the object, as well as ensuring that no foreign particles are left on the object after being demagnetized. [2]


How do you demagnetize small tools?

Demagnetizing small tools such as screwdrivers is actually quite simple. All you need to do is expose the tool to a strong electromagnetic field, which can be generated by an electromagnet or magnetized coil. The best way to get the job done is by wrapping a length of insulated copper wire around the tool and connecting it to a power source. When you turn the current on, it will create an electromagnetic field strong enough to demagnetize your tool in just a few seconds.

Can a screwdriver be magnetized?

Yes, a screwdriver can be magnetized. This is because it is made of iron and steel, which will become magnetized when exposed to a strong enough magnetic field. Fortunately, this process can also be reversed by exposing the tool to an even stronger electromagnetic field in order to demagnetize it again.

How long does magnetizing a screwdriver last?

The amount of time that a screwdriver remains magnetized after being exposed to an electromagnetic field depends on the strength of the field itself. Generally speaking, it should last for several days or weeks before the magnetic properties start to dissipate. However, this time frame can be extended by periodically exposing the tool to an even stronger magnetic field.

Can you magnetize a screwdriver with a battery?

Yes, you can magnetize a screwdriver with a battery in certain circumstances. This is because the chemical reaction taking place inside a battery creates an electric current that can be used to generate a magnetic field. All you need to do is connect the positive and negative terminals of the battery to either end of your tool and it should become magnetized in just a few seconds.

Are all screwdriver tips magnetic?

No, not all screwdriver tips are magnetic. Some types of screws and other fasteners require a non-magnetic tip in order to avoid any interference from the external environment. To determine if your tool has a magnetized or non-magnetized tip, simply hold it up against a metal surface and see if it sticks or not. If it does, then it’s magnetized; if not, then it’s non-magnetized.

How can you magnetize a steel screwdriver?

If you have a steel screwdriver that you would like to magnetize, the first step is to create an electromagnetic field by connecting a length of insulated copper wire to a power source. You can then wrap the wire around your tool and turn on the current, which will generate an electromagnetic field strong enough to magnetize your steel screwdriver in just a few seconds.

Do screwdrivers conduct electricity?

Yes, screwdrivers are made from metal and therefore do conduct electricity. This is why it is important to make sure that the power source you use to create the electromagnetic field is properly insulated from the tool in order to avoid any potential shocks or fires. Additionally, it’s also a good idea to wear protective gear such as gloves and safety glasses when working with electricity and magnetized tools.

Demagnetizing a screwdriver is an easy process that doesn’t require much time or effort. The tools you need, such as a strong magnet and hammer, are inexpensive and readily available at most hardware stores. It’s important to use the right technique for each tool so that they don’t become permanently damaged. By following these tips and taking the necessary precautions, you can ensure that your screwdriver is demagnetized safely and effectively. With a few simple steps, you can help keep your screwdrivers in top working condition for years to come.
