Abstract :
Analytic expression of axial stiffness between two ring permanent magnets with axial magnetization is given. This is performed with the aid of the axial stiffness calculating function of two coaxial ring disks with uniform charge distribution. The calculating function is expressed through elliptic integral of first and second kind respectively.
