Tech Hub on Instagram: "Ever wondered how a microwave actually works? 🍕 It all starts with the magnetron, which uses electricity to heat a tungsten filament and emit electrons. These electrons spiral through copper cavities, building up high-frequency microwave energy. This energy travels through a waveguide and into the cooking chamber, where it causes water molecules in your food to rotate millions of times a second. That rapid movement creates friction, which turns into the heat that perfect
