Manual demagnetization
Manual Demagnetization
Independent stand-alone solutions for your production
Many machined parts must not have any residual magnetism due to their subsequent use. If only individual assemblies or components are affected, plate demagnetisers are a cost-effective solution for manually removing residual magnetism.
Different manual demagnetizations are available for this purpose in terms of their effective area, depth effect and performance. The size and material composition of the component determine which device is required. This is because in order to achieve a good demagnetisation result, the component must be "penetrated" by the generated alternating magnetic field over its entire circumference.

TWO MAIN METHODS
For Manual demagnetization
The manual demagnetization process works by disturbing the alignment of the magnetic dipoles in a ferromagnetic material, thereby cancelling or reducing the magnetisation. This process can be carried out in different ways, but in general there are two main methods: alternating current and direct current demagnetization.
In AC demagnetization, the material is exposed to a rapidly changing magnetic field that changes at a high frequency. This field generates eddy currents in the material, which destabilise the magnetic field in the material and thus reduce or cancel the magnetisation.
In DC demagnetisation, the material is exposed to a strong magnetic field that is gradually switched off. The decreasing magnetic field generates eddy currents in the material, which disturb the magnetic field and thus reduce or cancel the magnetisation.
In both cases, it is important to gradually expose or remove the material from the magnetic field to prevent damage to the material. It is also important to adjust the strength of the magnetic field and the duration of exposure to the material to ensure complete demagnetization.
It is also worth noting that complete manual demagnetization of a material may not always be necessary. It is often sufficient to reduce the residual magnetisation to an acceptable level in order to use the material for certain applications.
The depth of effect
Important factor for effectiveness
The effective depth depends on various factors, such as the magnetic per meability of the material, the strength of the magnetic field and the frequency of the magnetic field. The higher the magnetic permeability of the material, the greater the effective depth. The higher the strength of the magnetic field and the frequency of the magnetic field, the lower the effective depth.
Each of the individual types is also available in different length dimensions (maximum component edge dimension), thus ensuring an optimum cost/benefit ratio. The standard dimensions are generally available from stock. Our plate demagnetisers can be found in small workshops as well as in large industrial companies.
