Why magnets stumped scientists for so long - Rachel Yang

Explore the physics of magnetism, and how its properties are used in modern technologies like MRI machines, hard drives, and more. -- In the 1920s, physicists still had many unanswered questions about magnetism. While they knew that every electron and proton have invisible, magnetic fields that radiate out in closed loops from one end to the other, they wondered: what determines the direction of these magnetic fields? And if every atom is composed of these tiny magnets, why isn’t everything magnetic? Rachel Yang investigates. Lesson by Rachel Yang, directed by Tolga Yıldız, Kozmonot Animation Studio.
