【 摘 要 】

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.
