  • They say lightning rods, lightning rods, do you know how lightning rods prevent lightning?

    In fact, lightning rods cannot avoid lightning at all. During thunderstorms, when electrified clouds occur on top of high-rise residential buildings, lightning rods and the tops of multi-story buildings magnetically induce a lot of electric charge. Because the lightning rod is pointed, the tip of...
