The principle of action and reaction in Lenz’s Law states that an induced electromotive force (emf) generates a current in a direction which opposes the change in flux that caused the emf in the first ...

As Lenz’s Law states, an inductor in a circuit opposes the flow of current through it because the flow induces an electromotive force (emf) that opposes it. In order to keep the current flowing ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
