PerMag 5.0

de Field Precision, Inc.

Permag (Ver. 5.0) is an advanced solution package for the design of permanent magnet devices. The program calculates static magnetic fields for any geometry with planar or cylindrical symmetry. Permag can perform combined runs with permanent magnets, coils and ferromagnetic materials. With its open data structure, the program handles all permanent magnet materials, including non-linear materials like Alnico. A concise users' manual reviews magnetostatic theory with anisotropic materials and numerical methods for field solutions. The included PerView postprocessor crates a variety of plots. Analysis capabilities include automatic determination of field energy, forces and induced current for inductance calculations. (Available for Linux and Windows. Mesh 5.0 required.)
