Modelica.Magnetic.FundamentalWave.Interfaces.PartialTwoPort

Information

This magnetic two port element consists of a positive and a negative magnetic port and considers the flux balance of the two ports. Additionally the magnetic potential difference (of the positive and the negative port) and the magnetic flux (into the positive magnetic port) are defined. This model is mainly to used to extend from in order build more complex - graphical - models.
