This vintage electrical meter is incredibly sensitive, and latches relay contacts with just 18 nanowatts!

A practical introduction to understanding magnetic devices such as transformers and motors. This video covers BH curves, reluctance, permeability, DC and AC magnetic circuits, and some applications.
Please put questions in the comments, and I'll do my best to answer them! I apologize that I didn't mention inductance.
This video focuses only on the magnetic side of things. Inductance is how the electrical circuit interacts with the magnetics.
