Information
The radial cylinder model is characterized by the outer diameter, 
, the inner diameter, 
, length, 
, and the angle 
. The magnetic reluctance is determined by:
In this model the magnetic flux and the magnetic potential difference, respectively, are radially oriented.
The above figure left shows a radial flux cylinder with 
. The figure on the right indicates the central angle in case a cylinder section shall be considered.
