What Makes a Magnetron So Incredibly Dangerous?

Hey guys! We’re now live on Spotify🎧 Listen here: https://open.spotify.com/show/3qYsIDs... Behind a metal panel in your microwave sits a sealed copper tube that has never touched the air. It tears electrons out of glowing metal, spins them through a vacuum, and sends out light so weak that no single particle of it could break a chemical bond. So why is it wrapped in warnings it never explains? Tonight we follow that tube from a wartime laboratory to your kitchen counter, through electrons, magnets, water and the quiet limits of the human body, one hidden layer at a time. Get comfortable and let this slow walk through the physics of the magnetron keep you company tonight. Subscribe to Lights Out Physics if you enjoy the long way around the universe.
