Magnetic Forces Between Two Permanent Magnets

Magnetic Field of 2 Cylindreical Permanent Magnets Background & Model Setup Many years back, part of my MS degree required me to do some modeling of some permanent magnets to get magnetic stiffness and magnetic flux. The code is based on the work done then. Other related ANSYS resources I found: CozyWork 's 2D single magnet model.  Ansys Help archive. Newer Ansys v18 has much of it undocumented.  K&J Magnetics has a really cool website calculator that computes the magnetic force of a few simple cases. The ANSYS script below computes the magnetic force between two magnets of N52, 10 mm diameter, 5 mm thick magnets. It is assumed the magnets have relative permeability of 1.05 and Coercive Force of > 11.2  kOe (> 89,1267 A/m). The model consists of the two cylindrical shaped magnets at a small distance from each other. Surrounding them is another cylinder that represents the air. Both are polarized in the positive Z direction thus the magnets ...
