Animation: Electrical induction 1

The following interactive animation illustrates the phenomenon of electrical induction.

The ladder can be moved. Click into the second rectangle and move the mouse. The 3D model is rotatable.

The animation on the left contains a 3D model with a horseshoe magnet. Inside the magnetic field there is a cylindrical conductor. The electrons are represented by blue spheres. The magnetic field of the horseshoe magnet can be switched on or off.

In the right area the objects are displayed in a profile view. In this view the ladder can be moved with the mouse. The displayed electrons in the left area then start to move continuously. In both areas also the dynamic magnetic fields are represented, which result from the movement of the charge carriers. If required, the resulting magnetic field can also be displayed in the right area.

The interactive real-time animation is suitable, among other things, for illustrating the hand rules, which are used as mnemonic devices.
