How to Magnetize a Screwdriver

Key Takeaways

  • Sliding a strong magnet along the screwdriver shaft is one of the most common and effective methods to magnetize a screwdriver.
  • Using wire and a battery is an alternative method to magnetize a screwdriver if a strong magnet is not available.
  • Hammering the tip of the screwdriver gently with a hammer can also induce magnetism in the screwdriver.

In this article, we will explore different methods to magnetize a screwdriver. Whether you’re a DIY enthusiast or a professional, having a magnetized screwdriver can make your work easier by attracting and holding screws. We will discuss several techniques recommended by experts and provide step-by-step instructions for each method. Let’s dive in and learn how to magnetize a screwdriver!

Method 1: Sliding a Strong Magnet

One of the most common and effective methods to magnetize a screwdriver is by sliding a strong magnet along its shaft. According to various sources, including WikiHow and Bob Vila, the following steps can be followed:

  1. Obtain a strong magnet, such as a neodymium or rare-earth magnet.
  2. Wipe any dirt or debris from the metal parts of the screwdriver.
  3. Hold the screwdriver in one hand and the magnet in the other.
  4. Slide the magnet slowly along the metal shaft of the screwdriver from the handle to the tip, repeating the motion several times.
  5. For optimal magnetization, give the tool a quarter turn and repeat the sliding motion four times.
  6. Test the strength of the magnetized screwdriver by touching it to a screw and observing how well it attracts and holds the fastener.

It is important to note that the screwdriver should stay magnetized for at least three months, but accidental drops can weaken the magnetism sooner. To intentionally demagnetize the tool, simply reverse the direction in which you drag the magnet along the screwdriver shaft.

Method 2: Wire and Battery

If you don’t have a strong magnet available, an alternative method involves using wire and a battery. As mentioned in the WikiHow article, you can follow these steps:

  1. Strip the ends of a wire and wrap it around the screwdriver.
  2. Touch the ends of the wire to a 6V or 9V battery for approximately 20-30 seconds.

This process induces magnetism in the screwdriver and allows it to attract and hold metal screws. However, it’s important to exercise caution when working with batteries to avoid any potential hazards.

Method 3: Hammering

Another interesting method, mentioned in the WikiHow article, involves using a hammer to magnetize a screwdriver:

  1. Point the screwdriver north.
  2. Gently strike the tip of the screwdriver with a hammer approximately 25-50 times.

This process aligns the magnetic domains within the metal and induces magnetism in the screwdriver. However, it’s important to exercise caution and use gentle force to prevent any damage to the screwdriver.


Magnetizing a screwdriver can greatly enhance your efficiency and convenience while working with screws. By following the methods mentioned above, you can easily magnetize your screwdriver and make your tasks more manageable. Whether you choose to slide a strong magnet along the shaft, use wire and a battery, or even try the hammering method, be sure to test the strength of the magnetized screwdriver before using it for your projects.

Q: What are the benefits of using a magnetized screwdriver?

Using a magnetized screwdriver allows you to attract and hold screws securely, making it easier to work with small metal objects or in hard-to-reach spaces. It also provides convenience and saves time by eliminating the need to fumble with screws.

Q: How can I magnetize a screwdriver using a permanent magnet?

To magnetize a screwdriver using a permanent magnet, rub the magnet along the screwdriver’s shaft. It is important to align the magnet’s poles with the screwdriver for effective magnetization.

Q: Can I magnetize a screwdriver using an electromagnetic field?

Yes, you can magnetize a screwdriver using an electromagnetic field. This method involves using an electromagnet, which requires an external power source. By setting up a coil of wire and passing electrical current through it, you can generate a magnetic field to magnetize the screwdriver. However, caution must be exercised when dealing with electrical components.

Q: What safety precautions should I follow when magnetizing a screwdriver?

When attempting to magnetize a screwdriver, it is important to follow these safety precautions: 1) Avoid magnetizing tools near sensitive electronic devices. 2) Be cautious with strong magnets to prevent injury or damage. 3) Properly store and handle magnetized tools to avoid unintended magnetization.

Q: Are there pre-magnetized screwdrivers available for purchase?

Yes, there are commercially available pre-magnetized screwdrivers. However, it is worth considering the pros and cons of purchasing pre-magnetized screwdrivers compared to magnetizing them yourself. Pre-magnetized screwdrivers offer instant convenience, but magnetizing them yourself allows customization and flexibility.
