demagnetisation
Magnetic field removal
Demagnetisation is the process of removing or reducing the magnetic properties of an object.
Metal tools, watch components, and electronic equipment may require demagnetisation when unwanted magnetism interferes with their function: The technician performed demagnetisation on the compass before recalibrating it.
Also spelled demagnetization.
