This information is part of the Modelica Standard Library maintained by the Modelica Association.
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.
