EI3350 Magnetic Hysteresis 8.0 credits

Magnetisk hysteresis

This course gives the participants knowledge of current hysteresis models of the magnetization of magnetic materials. It also renders the participants experience of using them in electrotechnical design applications.

  • Education cycle

    Third cycle
  • Main field of study

    P, F

Information for research students about course offerings

The course is given when there is sufficient demand. Please contact the examiner if you are interested in taking the course.

Intended learning outcomes

The aim of the course is to render comprehensive knowledge about current magnetic hysteresis models. Another goal is to the accomplish knowledge to select, apply and assess the appropriate hysteresis model in different applications of magnetic materials.

Course main content

  • The Preisach model
  • The Jiles-Atherton model
  • The Bertotti model
  • The Bergqvist model
  • Implementation and use of a selected model
  • Assesmemt of the used model


Self studies, Seminars, software exercises, project work , presentations of project, homework problems, written report

The written report should comprise a background and introduction of the topic of the course.

The different hysteresis models should be described and explained. In the report also an example of a computer implementation and application of a selected model should be given.


The participant must a registered PhD student in the program of Electrical Engineering


G. Bertotti: Hysterisis in Magnetism

I. Mayergoyz: Mathematical models of hysteresis
