You can easily magnetize a screwdriver using electricity or a magnet. This simple process takes just 5 minutes and can save you time and effort when dealing with screws. To magnetize a screwdriver with electricity, you'll need to strip the insulation from a wire, coil it around the screwdriver, and then attach the wire to a household battery. Using a magnet is even simpler: just slide a strong magnet from the screwdriver's handle to its tip. You can test the strength of the magnetism by seeing if the screwdriver can hold a metal screw.

What You'll Learn
Using a magnet
To test if the screwdriver is now magnetic, touch its tip to a loose metal screw. If the screwdriver can't hold the screw, repeat the process. If it still doesn't work after 10-15 passes on each side, try again with a stronger magnet. You can also try striking the screwdriver with a hammer 25-50 times before repeating the process with the magnet. Alternatively, you can use a wire and a battery to magnetize the screwdriver.
To demagnetize a screwdriver, simply slide the magnet in the opposite direction, from tip to handle, or strike the screwdriver against a wall or with a hammer to scramble its magnetic domains.

Using a battery
To magnetize a screwdriver with a battery, you will need a battery (preferably 6V or 9V), a screwdriver, and a piece of wire. Start by stripping the insulation from the ends of the wire. Then, wrap the wire around the screwdriver 10-20 times, making sure to wind every loop in the same direction. Once the wire is wrapped around the screwdriver, attach one end of the wire to the positive terminal of the battery and the other end to the negative terminal. Hold the wire and battery together for 20-30 seconds. The current flowing through the wire will create a magnetic field, which will magnetize the screwdriver.
It is important to take safety precautions when performing this task. Wear insulated gloves to protect yourself from shocks and sparks. Make sure to work with rubber gloves and never touch anything electrical with more than one hand at a time. If you are using a higher voltage battery, such as a 12V car battery, be extra cautious as these batteries can be dangerous if not handled properly.
After you have held the wire and battery together for the recommended time, disconnect the battery. The screwdriver should now be magnetized and able to pick up screws. If the screwdriver loses its magnetism after disconnecting the battery, wrap a few more loops of wire around it and try again.
You can also use a stronger battery, such as a 12V car battery, to magnetize a screwdriver. However, higher voltage batteries should be used with caution and only by those with experience in handling them safely. With a stronger battery, you only need to connect the wire and battery for a brief moment to magnetize the screwdriver.
By following these steps and taking the necessary safety precautions, you can successfully magnetize a screwdriver using a battery.

Using an electromagnet
The next step is to prepare the wire. Cut a piece of wire that is at least 7 inches (18 cm) long, and strip about an inch (2.5 cm) of insulation off each end. Thinner insulation will enable stronger magnetization, and enamel-coated wire is ideal. To strip the enamel, rub the ends of the wire with 220-grit sandpaper.
Now, coil the wire around the screwdriver shaft 10 to 20 times, ensuring the wire is tight. If your screwdriver is too short, double back for a second layer, but maintain the same coiling direction. For example, you can coil left-right-left, but each loop should be wound clockwise. Tape the wire in place if needed.
Finally, attach the wires to a household battery for 20-30 seconds. Use a 6V or 9V battery, touching one end of the wire to the positive terminal and the other to the negative simultaneously. This will create an electromagnet, and your screwdriver should now be magnetized.
To test the magnetism, touch the tip of the screwdriver to a loose metal screw. If the screwdriver can't hold the screw, repeat the process. A steel screwdriver should stay magnetized for months. To demagnetize the screwdriver, simply run the magnet in the reverse direction, from the tip to the handle.

Safety precautions
It is important to take certain safety precautions when attempting to magnetize a screwdriver with electricity. Here are some essential guidelines to follow:
Rubber Gloves and Eye Protection: When working with electricity, it is always recommended to wear rubber gloves to protect yourself from electrical shocks. Additionally, wearing safety glasses or goggles is crucial to safeguard your eyes from potential sparks or debris.
Single-Handed Contact: As a general rule, never touch anything electrical with both hands simultaneously. This precaution is crucial because a shock across your heart can be far more dangerous than a shock across your hand. Keep this rule in mind to minimize the risk of electric shock.
Voltage Awareness: Be mindful of the voltage you are working with. While 27 volts may not be sufficient to cause a shock under typical circumstances, higher voltages can be hazardous. Always assess the voltage before proceeding, and if you are unfamiliar with higher-voltage equipment, seek guidance or assistance.
Wire Selection: Choose a reasonably thick insulated wire for your project. A wire with a gauge of at least 18 is recommended, but if possible, opt for 12-gauge solid-copper home wiring. Thicker wires, such as 16–22 AWG (1.3–0.6 mm diameter) wire, can also be considered. Enamel-coated wire tends to yield the best results.
Battery Safety: When attaching wires to a battery, opt for a 6V or 9V household battery. Higher-voltage batteries should be avoided unless you have experience handling them safely. Always disconnect the battery promptly after use, as the wire and battery terminals can heat up quickly.
Magnet Direction: Remember that the direction in which you move the magnet matters. To magnetize the screwdriver, always slide the magnet from the handle to the tip. Reversing the direction, from tip to handle, will demagnetize the tool.
By adhering to these safety precautions, you can confidently attempt to magnetize your screwdriver using electricity while minimizing potential risks.

Testing magnetism
Once you have magnetized your screwdriver, you can test its magnetism in several ways. Firstly, you can test it by simply trying to pick up a screw. Alternatively, you can test for magnetism by sliding a magnet along the shaft of the screwdriver. If the screwdriver is magnetized, the magnet will stick to it.
You can also test the strength of the screwdriver's magnetism by observing how many screws it can hold at once. A stronger magnetic field will be able to hold more screws.
It is important to note that banging or knocking a magnetized screwdriver can cause it to slowly lose its magnetism. Therefore, if you plan to test the magnetism of your screwdriver by striking it with a hammer, as described in the previous steps, you should be aware that this may affect the results of your test.
Additionally, the type of screwdriver you use can impact the results of your test. A hard steel screwdriver, for example, will typically stay magnetized for longer periods, while a screwdriver made of a different material may lose its magnetism more quickly.
Finally, the method you use to magnetize the screwdriver can also impact the results of your test. For example, using a stronger magnet or repeating the sliding motion more times will generally result in a stronger magnetic field. Conversely, using a weaker magnet or sliding the magnet back and forth along the shaft of the screwdriver may result in a weaker or non-existent magnetic field.
