Permanent magnet demagnetization at high temperature
Application ID: 153291
Permanent magnet manufacturers will place the magnets in a high-temperature oven to apply cyclic temperature loading during the magnet design process, to observe the demagnetization state of the magnets. The heating process is usually so slow that the temperature distribution inside the magnet can be considered uniform. As a demonstration case, this case simulates the demagnetization state caused by the temperature rise in this process, and can serve as a quickly reference case for relevant users to learn. If the influence of temperature non-uniformity is considered in subsequent work, solid heat transfer can be easily added to this case. The modeling idea in the model and the BH curve data are available from the case : https://cww.comsol.com/models/modelinfo/?id=139621
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabella delle Funzionalità and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
