SCIENCE | FACTS | KNOWLEDGE on Instagram: "This floating ring looks like magic — but it’s actually physics doing exactly what it’s supposed to do. 🧲✨ No strings. No tricks. Just invisible forces at work. The effect comes from a balance of magnetic fields and induced currents. When an alternating magnetic field passes through a conductive ring, it creates an eddy current inside the metal. According to Lenz’s Law, that induced current produces its own magnetic field that opposes the original one.
