Magnetic simulations

Complex magnet systems made of permanent magnets are widely used, for example in electric motors and magnetocaloric systems. Due to the special arrangement in so-called Halbach arrays, field strengths of over one Tesla can be generated by using permanent magnets. The flux densities in such Halbach arrays can be tuned using relatively simple measures.

We carry out simulations using the finite element method in order to design such magnet systems. The objective is to optimize the systems, for example with regard to field strength or forces, use of materials or even size. Losses caused by stray fields can also be calculated and minimized. Magnet systems can be designed, manufactured, built and characterized based on these simulation results.

We use our expertise in finite element method simulations of magnet systems primarily for the development of magnetocaloric systems, but we also offer this as a service.
