Abstract :
In Lorentz force evaluation the model of the permanent magnet influences the accuracy of the forward solution. We assess the forward solution by modelling the permanent magnet with a varying number of magnetic dipoles. Our model comparison shows that a model with 10 dipoles is well suited for the forward calculation of Lorentz forces.
