Subject it to an alternating magnetic field with decaying amplitude. (ie: run AC though any coil/loop with your tool next to it, and slowly move the tool away).Q_Goest said:
That's the same way I manually degaussed a TV tube.Gokul43201 said:
Probably the optimum is a peak magnetic field from the coil that is just a bit bigger than the magnetization of the object. The peak magnitude of the degausing field has to be bigger than the magnetization of the object so that it can drive the magnetization at least a bit the other way. You can make the degausing field a lot bigger, but that takes more power and it's more likely that you might accidentally degaus something important like your credit cards...Mk said:
A non magnetic screwdriver magnetized is a screwdriver that has been treated with a magnetic field to temporarily become magnetic. This allows the screwdriver to attract and hold onto metal screws, making it easier to drive them into place.
A non magnetic screwdriver can be magnetized by rubbing it against a magnet or by using an electromagnetic field. This causes the metal in the screwdriver to become temporarily magnetized and able to attract metal objects.
A non magnetic screwdriver magnetized can make it easier to handle and drive screws, as they will be attracted and held onto by the screwdriver. This can save time and frustration when working with small or hard-to-reach screws.
It is possible for a non magnetic screwdriver to become magnetized permanently if it is exposed to a strong enough magnetic field for a prolonged period of time. However, this is not common and can usually be reversed by demagnetizing the screwdriver.
To demagnetize a non magnetic screwdriver, you can run it back and forth along a piece of steel in the opposite direction of how it was magnetized. You can also use a demagnetizing tool or expose the screwdriver to a strong alternating magnetic field.
