Magnetism | Can’t Sleep? Discover the Power of Attraction
Summary
Host Benjamin Bo explores the physics and history of magnetism, explaining how magnetic fields cause attraction and repulsion. The episode details the discovery of lodstones in ancient Greece and China, as well as key scientific breakthroughs by figures like William Gilbert, Hans Christian Oersted, and James Clerk Maxwell. It distinguishes between ferromagnetic, paramagnetic, and diamagnetic materials, describing how electron spins and magnetic domains create permanent or induced magnetic fields.
