A demagnetizer is a device that removes magnetic charge from an object. However, there are various synonyms for this word. First, a demagnetizer can also be called a degausser or demagnetizing machine. Additionally, in some contexts, it may be referred to as a demagnetizing wand or demagnetizing coil. Other synonyms include demagnetizing field, magnetic field eraser, and demagnetizing bar. These terms are often used interchangeably and can refer to the same process of removing magnetism from an object. No matter the terminology used, the end result is the same: a demagnetized object that is free from magnetic charge.
