The question of how the processes around the Faraday generator with its rotating magnet should be interpreted has been controversial since its discovery by Faraday. Does the magnetic field rotate together with the rotating magnet or does it rema[...]Article
In this work, an easy-to-set-up demonstration about electromagnetic induction is presented, where a simple toy electric motor is transformed into a musical instrument. With this creative way to mix physics and music, it is expected to engage and[...]Article
In an earlier article I argued that much of what used to be called “modern physics” stems from the intersection of two earlier technologies: high vacuum and high voltage. In this article I will discuss the induction coil, invented in the 1830s, [...]
