Why You Can't Actually Cut a Magnet in Half ?|Brian Greene Explains

Cut a magnet in half and you don’t get a north pole and a south pole. You get two smaller magnets, each with both poles. Cut those in half again and the same thing happens. Why does this keep happening, and is there any way to isolate a single magnetic pole? In this video, physicist Brian Greene explains why magnets always come with two poles, and what that tells us about electromagnetism and the structure of matter. The key ideas: 🧲 Why every magnet has both a north and a south pole 🔬 How the magnetism of a material comes from the motion and spin of electrons ⚛️ Why cutting a magnet only creates smaller magnets, all the way down to individual atoms 🌌 What magnetic monopoles are, why physicists have searched for them, and why finding one would change physics ⚡ How electricity and magnetism are two sides of the same fundamental force Whether you are a student, a science enthusiast, or just curious about how the world works, this video offers a clear, accessible look at one of the most common puzzles in physics. 👍 If you found this video helpful, please like, share, and subscribe for more explanations of physics, the universe, and the ideas shaping modern science. 💬 Tell us in the comments: did you know you couldn’t separate the poles of a magnet?
