The Secrets of Magnetism Unveiled: Exploring the Mysteries of Magnetic Fields

TLDRMagnetism is a fascinating phenomenon that allows objects to attract at long distances. Magnetic fields are generated by the movement of electrically charged objects. At the atomic level, particles like electrons have an intrinsic magnetic moment. The magnetic behavior of everyday objects is influenced by the combination of effects at the particle, atom, and crystal levels. Domains within a material determine its overall magnetic properties. Understanding magnetism requires a deep dive into quantum mechanics. Check out this video to unravel the secrets of magnetism and how it connects to electromagnets and special relativity.
