Web8 de jul. de 2024 · Permanent magnet demagnetization is the change in the remanence (the magnet’s strength) and the coercivity (the field needed to demagnetize it completely) of magnets (see Figure 1). The changes can happen from elevated temperature or if a high enough magnetic field opposes the magnet’ intrinsic fields (due to electrical faults). WebThe magnets are arranged so that as an item bearing magnetic security strips passes through the frame it encounters several orthogonal magnetic fields, each succeeding field being weaker than the preceding field. The patent explains that each field is able to demagnetize security strips which lie approximately parallel to that field. WebA magnetic material can be demagnetised using the following methods: Heating the product to above the Curie temperature. Strong vibrations (hammer blows) that can cause a slight reduction in magnetisation due to their own magnetic field.
