The aim of my bachelor thesis is creating a model with ferromagnetic parts of speed sensor and than FEM (finite element method) simulation of magnetic field. In my work I will be dealing with simulation of ferromagnetic parts in interaction with static magnetic field generated
by permanent magnet. I will try to design magnet, that would work in temperature range from -40 deg C to +260 deg C and at the same time it would generate sufficient difference of magnetic flux densities according
to position of ferromagnetic part. Ideally the difference should be 10 mT or more, so that we can easily measure and evaluate speed of rotation by Hall sensor.
