The AC Generator (Derived from First Principles Physics)

The AC Generator (Full Visual Explanation, derived from First Principles)

Welcome back to the second video in my series on the Fundamentals of AC Electricity. In this video, we investigate the AC Generator Construction, highlighting the working principle behind it. We uncover how Electromagnetic Induction, via Faradays Law, is the key driving force behind it. We derive the machine from first principles, starting with fundamental physics, and building a machine around it. In turn, we derive the sinusoidal equation of an alternating voltage source and magnetic flux.

PS this video was a lot of fun to make, and one of my proudest! Hopefully it makes this topic, which used to be extremely confusing for me, click for you.
