Energy Doesn’t Flow IN Wires! (The Poynting Vector Explained)

Описание: Most of us were taught that electrical energy flows through the copper inside a wire. It turns out, that’s not entirely true. In this video, we dive into one of the most mind-bending concepts in physics, popularized by the legendary Richard Feynman.

Using the concept of the Poynting Vector, we explore why energy actually travels through the electromagnetic fields surrounding the wire, rather than inside the metal itself.

What’s inside this video:

The Field Truth: Why the space outside the wire is more important than the wire itself for carrying power.

Electrons vs. Energy: Understanding the difference between slow-moving electrons (Drift Velocity) and the near-instantaneous flow of energy.

Feynman’s Insight: How one of the greatest minds in history simplified a complex Maxwell equation into a concept anyone can visualize.

If you’ve ever wondered how a battery actually powers a bulb across a room almost instantly, this explanation will change the way you look at the world around you.
