Intrinsic Spin

In classical physics, we imagine spinning objects like tops or planets. But in quantum physics, particles have a special kind of “spin” that isn’t really about physical spinning. It’s an intrinsic property of particles, just like mass or charge.

This quantum spin can have values like “up” or “down.” Even though we can’t see the particle spinning like a ball, spin affects how particles behave in magnetic fields and how they interact with each other.

Spin is also key to how we build technologies like MRI machines in hospitals and how we understand quantum computers.
