MODELLING THE MAGNETIC FIELD DISTRIBUTION IN THE MAGNETIC SUSCEPTIBILITY BALANCE DESIGN

Alicja Praczukowska – Micha³ Nowicki – Jacek Salach – Roman Szewczyk

   The following paper describes the modelling of the magnetic field distribution during the design phase of a new magnetic susceptibility balance. Various permanent magnets arrangements were tested, to find one with the closest to linear magnetic field gradient area. The modelling was performed with the Whitney elements method and magnetostatic Maxwell equations using the free open-source Elmer FEM software. The software shows significant flexibility and allows for user-defined solvers, methods and equations. The meshes were made with the open-source Netgen 5.3. The spatial distribution of the calculated magnetic field is presented in both cases: with and without the sample.

Keywords: magnetic field modelling, magnetic susceptibility balance, finite element method
