Material Libraries
The AC/DC materials library contains a number of materials that assist in modeling electromagnetic components such as actuators, motors, loudspeakers, generators, and so on. Two branches of material, AC/DC () and Nonlinear Magnetic () in the Material Library (), are frequently used. The AC/DC branch includes typical materials for electromagnetics modeling and the Nonlinear Magnetic branch includes nonlinear magnetization curves for a large set of ferromagnetic alloys.
For detailed information about Materials including the AC/DC Material Library and Nonlinear Magnetic Materials Library, see the COMSOL Multiphysics Reference Manual.
The AC/DC Material Library contains the material property data from the following company’s products:
