Magnetpendel - Simulation of a pendulum with iron sphere above a plane with magnets


This program simulates the movement of a magnetic pendulum above a plane with magnets. This experiment is a prototype of simple physical systems that can show chaotic behavior.

The program calculates both the pendulum movement (trajectory) and the basins of the initial values, which result in a fractal pattern for certain parameter settings. Thus, the connection between chaos and fractals can be seen very clearly here. Multiple parameters can be adjusted freely, making it easy to perform different types of analysis
