Written by Tony R. Kuphaldt and Jason Starck, this chapter of All About Circuit's second volume on Alternating Current describes complex numbers: "In order to successfully analyze AC circuits, we need to work with...

The effect of the commutator is to produce a fixed spatial distribution of current directions in the armature conductors (shown as blue & green circles) independent of shaft rotation. The field created by these currents...

All About Circuits is a website that “provides a series of online textbooks covering electricity and electronics.” Written by Tony R. Kuphaldt, the textbooks available here are wonderful resources for students, teachers,...

This site from the Exploratorium provides a simple demonstration of the interaction between a moving magnet and its induced electromagnetic field. As the magnet is dropped down a metallic tube, it induces eddy currents...
