Make a regular steel screwdriver hold small screws with a strong permanent magnet, a clean shaft, and repeated strokes in one direction.
The fast way to make a screwdriver magnetic
When you are fitting cabinet hardware or reaching into a recessed appliance panel, a tiny screw falling off the driver is more than annoying. A quick pass with a strong permanent magnet can give many steel screwdriver shafts enough pull to hold a small steel screw at the tip.
This works because the magnet encourages magnetic domains in suitable ferromagnetic steel to line up. You do not need a complicated setup: a clean screwdriver, a decent permanent magnet, and steady repeated strokes are usually enough for an everyday DIY job.
What you need before you start
A stronger magnet generally gives a better result. A small neodymium magnet is effective, but a strong ceramic or bar magnet can also work. The screwdriver must have a steel shaft that responds to a magnet; not every stainless alloy will respond strongly.
The direction matters: handle end to tip
Use the same direction for every pass. Begin near the handle end of the exposed metal shaft and stroke down toward the working tip. Lift the magnet away before returning to the top. Random back-and-forth rubbing can weaken the result because it does not consistently encourage the domains to align.
How to magnetize a screwdriver with a magnet
Clean the shaft and screwdriver tip
Wipe away oil, metal filings, paint dust, and loose dirt. A clean tip makes the test more reliable and prevents debris from getting transferred into a screw recess.
Set the magnet near the handle end
Hold the screwdriver still on the bench or in one hand. Touch one face or pole of the magnet to the metal shaft near the handle, not the plastic handle itself.
Stroke smoothly toward the tip
Draw the magnet along the shaft toward the tip 20 to 30 times. Use steady contact and one direction each time. At the tip, lift the magnet away before returning to the starting position.
Test and strengthen if necessary
Touch the screwdriver tip to a small steel screw. If it holds securely enough for your job, you are done. If the pull is weak, make another 10 to 20 one-way strokes with the same magnet.
Test the magnetic pull before the real job
Use a small, lightweight steel screw—the sort used for cabinet pulls, switch plates, PC cases, or appliance covers. The screw should cling to the screwdriver tip long enough for you to guide it into place without using your other hand to steady it.
In a realistic cabinet-hardware job, a magnetized Phillips screwdriver lets you place the screw into a recessed hole while keeping the screw engaged with the driver. It is helpful, but not a substitute for supporting a heavy fastener or working safely overhead.
A practical expectation
The goal is useful holding power, not a permanently powerful tool. Magnet strength, the screwdriver steel, shaft shape, and the screw material all affect the result.
If your screwdriver is only weakly magnetic
Most weak results come down to magnet strength, dirty contact surfaces, or a shaft that does not magnetize easily. Try the practical fix below before assuming the method failed.
| What you notice | What to try |
|---|---|
| The screw barely sticks | Clean the shaft and tip, then add 10 to 20 more strokes in the same handle-to-tip direction. Use a stronger magnet if available. |
| The magnet does not attract the shaft | The shaft may be a non-magnetic alloy or have too little ferromagnetic material. Try a different screwdriver rather than forcing the process. |
| A brass or stainless screw will not hold | Many brass and some stainless fasteners are non-magnetic. Test with a known steel screw; the screwdriver may be magnetized even when that particular screw will not stick. |
How to demagnetize a screwdriver
For the most predictable result, use a purpose-made magnetizer/demagnetizer and follow its manufacturer instructions. These small tools usually have separate slots that let you magnetize or reduce magnetism with a few passes.
At home, you can often reduce the pull by moving the screwdriver through an alternating magnetic field or by lightly tapping the shaft while gradually moving it away from a magnet. Results vary, so test with a steel screw afterward. Electrical magnetizing or demagnetizing setups exist, but they are unnecessary for this everyday DIY task.
Magnetic screwdriver FAQs
Can any screwdriver be magnetized?
No. A screwdriver needs enough ferromagnetic material, usually steel, for the effect to be useful. If the shaft is not attracted to your magnet at all, it is unlikely to become meaningfully magnetic.
How long does a magnetized screwdriver stay magnetic?
It can last from a short while to a long time depending on the steel, magnet strength, shocks, heat, and everyday use. Treat it as a useful temporary or semi-lasting effect and repeat the one-way strokes whenever the pull becomes too weak.
What type of magnet works best?
A strong permanent magnet works best for the DIY method. Small neodymium magnets are very effective; a strong ceramic, bar, or salvaged speaker magnet may also work. Keep powerful magnets away from objects that could be damaged by magnetic fields.
Can magnetizing damage my screwdriver?
Normal magnetizing with a hand-held permanent magnet should not damage a sound screwdriver. It does not sharpen the tip or change the screwdriver size. Avoid striking the tool unnecessarily, and replace a worn or rounded driver tip as you normally would.
