TP IV-Report : Study of isotropic and anisotropic particles composed systems

Sealskin is used for the practice of cross-country skiing. In order to stick it to the ski one must use a special glue that is very sticky and hard to remove from the ski, and also it gets non-sticky if the glue is wet. In order to tackle this problem, a project has been submitted to the LQM laboratory in order to investigate a sealskin with nano-particle permanent magnets that will stick it to the skis. The aim of this report is to compare the eficiency, in terms of magnetic field generated by the magnets, of isotropic and anisotropic nano-particles of NdFeB. To do so, one will simulate, with the help of Ansys' Maxwell3D mode, three composition of magnetic powder : 100% isotropic particles, 100% anisotropic particles and 50% isotropic and 50% anisotropic particles.
