demagnetiseerimine
Demagnetiseerimine, also known as degaussing, is the process of reducing or eliminating a magnetic field. This is typically achieved by exposing a ferromagnetic material to an alternating magnetic field that gradually decreases in strength. As the external magnetic field alternates, the magnetic domains within the material are repeatedly rearranged, eventually aligning in random directions, thus canceling out any net magnetic moment.
The most common method involves passing the object through a coil carrying an alternating current. The strength
Demagnetisation is important in various applications. For instance, it is used to remove residual magnetism from
