Energy Doesn’t Travel Inside Wires — Here’s Why | Leonard Susskind

Most people believe electricity travels inside a wire. But according to physics, that’s not what actually happens. In this fascinating lecture, Leonard Susskind explains one of the most misunderstood ideas in electromagnetism: energy doesn’t flow through the copper the way you think it does. Instead, the real energy transfer happens in the electromagnetic fields surrounding the wire — not inside it. Using Maxwell’s equations and deep physical intuition, Susskind walks through how electric and magnetic fields interact to carry energy through space. You’ll discover: • Why current in a wire is NOT the same as energy flow • How the Poynting vector explains real energy movement • Why energy travels outside the conductor • What electromagnetic fields are really doing • How this changes your understanding of circuits This lecture will permanently change how you think about electricity, energy, and even everyday devices. If you’ve ever taken physics, studied circuits, or simply wondered how electricity truly works — this is the explanation you were never given. ⏱️ Time Stamps (36:31 Total) 00:00 ⚡ Introduction – The Big Misconception 02:15 🔌 What We Think Happens in a Wire 05:40 🧲 Electric & Magnetic Fields Explained 09:10 📐 Maxwell’s Equations & Energy Flow 13:20 🔄 The Poynting Vector – The Real Story 17:45 🌊 How Energy Moves Around the Wire 22:10 🔬 What’s Happening Inside the Conductor 26:30 💡 Why This Changes Circuit Theory 30:00 🌌 Fields Are Fundamental 33:15 🧠 The Deeper Meaning for Physics 36:31 🚀 Final Insight & Takeaway 🔑 20 Keywords (One Paragraph, Comma Separated) Leonard Susskind, electricity explained, energy flow in wires, Poynting vector, electromagnetic fields, Maxwell equations, physics lecture, electric current vs energy, how electricity works, theoretical physics, energy transfer, electromagnetic theory, circuit physics, field theory, spacetime fields, energy outside wire, physics education, advanced physics concepts, electromagnetism lecture, physics misconceptions 🔥 20 Hashtags (One Paragraph) #LeonardSusskind #Physics #Electricity #Electromagnetism #MaxwellEquations #PoyntingVector #QuantumPhysics #TheoreticalPhysics #EnergyFlow #ScienceExplained #PhysicsLecture #STEM #CircuitTheory #FieldTheory #ScienceEducation #CosmicTruth #PhysicsFacts #UniversityLecture #MindBlown #DeepPhysics 🔎 5 Top Searches for This Topic How does electricity actually flow in a wire?
