How demagnetize a magnet
WebThe magnetism holds screws firmly to the tool and allows them to be set easily without having to use a second hand. Even if you loosen a screw, the magnetic effect ensures that it does not get lost after unscrewing it. However, for work that you absolutely must carry out without a magnetic field, you should demagnetize your tool before use. WebScore: 4.8/5 (48 votes) . Objects that are magnetized will remain that way until you demagnetize, or degauss it. ...However, degaussing is not entirely fool-proof. It can only be used on magnetic media, and there is no way to guarantee that a particular degaussing machine is strong enough to destroy all the data on every hard drive.
