The Quantum Field: Where Magnets Actually Get Their Power | Brian Greene Explains

Magnets seem simple, yet their power comes from one of the deepest ideas in physics. In this video, we explore how quantum fields help explain magnetism and why invisible forces acting across empty space are connected to the fields that form the foundation of our physical reality. Moving beyond the familiar picture of "invisible field lines," this video explores how electromagnetism emerges from quantum field theory, why modern physics considers fields fundamental, and how an everyday magnet can reveal deeper ideas about the structure of the universe. In this video, you will learn how magnets exert force across empty space, what quantum fields are and why they matter, how electromagnetism emerges from quantum field theory, why fields are considered fundamental in modern physics, and what magnetism can reveal about the nature of reality.
