Abstract
An experiment has been performed on a magnetic pendulum, which interacts with an electromagnet. The free non-linear vibrations of the pendulum-magnet system are studied to identify and analyse the system’s characteristics. Due to the presence of the electromagnet, a modulation of the pendulum’s natural frequency is observed. A mathematical model is formulated that is able to reproduce the experimental results.
