Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Flux tube element for modeling the hard magnetic hysteresis of permanent magnets. The model is similar to GenericHystTellinenHard but has an initial magnetization preset of -100% and an adapted icon for better readability of the diagram.
An overview over all available hysteresis and permanent magnet elements of the package HysteresisAndMagnets can be found in UsersGuide.Hysteresis.
