Computer simulation using the finite element method can determine the magnetic forces with various boundary conditions, but usually it is not convenient for industrial users. Based on the large database generated by using 3D computer simulation, Quadrant worked the Maxwell magnetic force equation that is user friendly to obtain the force by simply inputting the magnet’s Br, area and thickness.
