The Mystery of Magnetism: Why It Stumped Scientists

In the 1920s, physicists still grappled with fundamental questions about magnetism. They knew that electrons and protons have magnetic fields, but what determines their direction? And if every atom is a tiny magnet, why isn't everything magnetic? This video explores the history of magnetism and the scientific breakthroughs that eventually answered these questions. We delve into the quantum mechanics of spin and how it gives rise to magnetic properties. The episode also covers the practical applications of magnetism, from MRI machines to hard drives, and how our understanding has led to technological revolutions. Educator Rachel Yang explains the concepts with clarity and enthusiasm. By tracing the journey from confusion to comprehension, the video highlights the importance of curiosity and persistence in science. It's a compelling narrative of how a mysterious force became a cornerstone of modern technology.
