# Electromagnetic induction by rotating magnets

The interactive animation illustrates the principle of electromagnetic induction using the example of a rotating magnet.

The 3D model is rotatable.

You can zoom in and zoom out the rectangle in the animation by clicking on it.

The animation was developed as a offline application for Windows and Macintosh systems and for integration into Microsoft PowerPoint slides. The online version presented here serves as a preview. The exe or app file can be downloaded free of charge in the member area.

Nach dem Download kann die Animation im Vollbildmodus angezeigt werden. Auch die Einbindung in PowerPoint ist möglich.

## Description

The animation contains four areas with the following content:

AreaDescription
top left3D model of a conductor and a rotating magnet. Inside the conductor, electrons are represented. As the magnet rotates, the electrons in the conductor are set in motion.
top rightThe 3D model in a profile view. The technical current direction is represented by symbols. In addition, the field lines of the magnetic field can also be displayed.
bottom leftThe curve shows the height of the induced voltage over time. The curve is dynamically updated.
bottom rightThe formula shows how the induced voltage is calculated.
