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 Material Library, see the COMSOL Multiphysics Reference Manual.
The Liquid Metals folder in the AC/DC material library branch contains values for the Thermal conductivity, Electric conductivity, Dynamic viscosity, and Density for liquid Titanium, Steel, Iron, Nickel, Copper, Aluminum, Magnesium, Tin, Lithium, Sodium, Wood’s metal, Potassium, Gallium, NaK (Sodium-potassium eutectic), and Mercury based on the book Introduction to Magnetohydrodynamics by P.A. Davidson, published by Cambridge University Press.

The Biological Tissues folder in the AC/DC material library branch contains values for the Electric conductivity, the Relative permittivity, and the Reference temperature, together with the Relaxation times and Relative permittivity contributions of several Debye poles, for 54 biological tissue types. This data can be used together with the Multipole Debye dispersion material models, and is taken from Ref. 1.
The AC/DC material library also contains material property data from the following companies’ products:
