Equations for the approximate calculation of forces between cuboid magnets
Werner Karl Schomburg, Olivier Reinertz, Johannes Sackmann, Katharina Schmitz
Abstract
Equations are presented roughly describing the forces between cuboid magnets in normal and lateral direction as a function of their relative position. The equations are adapted to the forces measured with a tensile testing machine and obtained from finite element calculations. From the conservation of energy, a relationship between the magnetic forces in normal and lateral direction is derived. The equations may help designing machines containing solenoids or permanent magnets.
