How demagnetize a magnet
Web17 de fev. de 2015 · 1. You should take an electromagnet that operates on some frequency (tens of Hertz) and creates enough large magnetic field to magnetise your … 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.
