The Computation of the Dynamic Inductance of Magnet Systems and Force Distribution in Ferromagnetic Region on the Basis of 3-D Numerical Simulation of Magnetic Field

摘要

Static and dynamic inductances are ones of the main technical parameters of magnet systems at the designing stage. Pondero-motive force distribution is required for mechanical stress calculations. The static inductance is used for evaluations of the stored energy, magnetic flux linkage in coils at instantaneous currents. The dynamic inductance allows to define the interrelation between the instantaneous flux linkage and currents determining a transient process in coils.
