| Abstract: | The attractive behaviors of instantaneous release are calculated by two methods:magnetic field computation and magnetic circuit computation. Software VECTOR FIELDS was used to set up 3D finite element model, and a magnetic circuit model was built specially for instantaneous release. The dynamic behaviors were computed combined with the electric circuit equation. |
