A Tiny Magnet Sneaks Through an Invisible Wall ⚡ экспресс

In the quantum world, even a spinning magnet can pass through an invisible wall — and scientists are preparing to see it live.

A tiny magnet in a trap tries to spin but hits an invisible wall. In the quantum world, it could seep through it, but residual air gets in the way. But if you make the magnet symmetric, like a ball, that quantum magic becomes visible. Soon we could create detectors of unprecedented sensitivity.
🎯 Quantum tunneling through a barrier is routine for microparticles. But for a magnetized sphere that suddenly flips the other way without intersecting the wall — it's like watching a ball pass through a brick.
