Abstract
In this work, a low-frequency dynamic hysteresis model is proposed and applied to nonoriented Fe-Si steel. The model based on Preisach theory can be used when skin effect is negligible over the lamination thickness. In our model, the Preisach engine that usually takes the magnetic field as input variable must be inverted. Some B(H) symmetric loops are calculated and compared with measurements in the rolling direction both in quasistatic and dynamic operations under sinusoidal induction.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
