# Teaching animation: Principle of electromagnetic induction

The following interactive animation illustrates the processes that are generated during the creation of an electrical current via motion energy.

The conductor can be moved. To do this, click the second rectangle and drag mouse cursor.

The 3D model is rotatable.

You can scale the two areas by clicking on them.

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

After the download, the animation can be shown in full screen mode. Integration into PowerPoint is also possible.

## Description

On the left side the animation contains a 3Dmodel showing a horseshoe magnet. Placed inside the magnetic field is a cylindrical conductor. The electrons are represented by blue dots.

On the right, the objects are shown in profile. In this position, the conductor can be moved using the mouse. The electrons on the left will start to move in a continuous manner. The dynamic magnetic fields generated by the movement of the electrons are also present in both areas. If required, the resulting magnetic field in the right region can also be shown.

The interactive real-time animation can be used as a mnemonic aid, to illustrate the formation of the dynamic magnetic field and indicate the direction of movement of the electric current.
