Physics Uncovered on Instagram: "This is electromagnetism — one of the four fundamental forces of the universe. 🌌 When electric current flows through a wire, it creates a magnetic field around it. Wrap that wire into a coil, and the field strengthens — turning electricity into magnetism. Add an iron core inside, and you get an electromagnet powerful enough to lift cars or move train tracks. That same principle powers everything from your phone’s speakers and motors to MRI machines and maglev tr

UNIVERSE | SCIENCE | TECHNOLOGY on Instagram: "🔋🧲 Electromagnetic Force in Action! When electricity flows through a wire near a magnet, it creates a magnetic field that pushes or pulls — that’s the electromagnetic force! 💥 Using just a battery, wire, and magnets, you can make the battery move on its own. This simple experiment shows how electricity and magnetism combine to create motion — the same principle used in electric motors! ⚡ Follow @explaining.science__ #ElectromagneticForce #Science
