The Motor Effect _ GCSE Physics
When a current passes through a wire it produces a magnetic field. If you put this magnetic field in another magnetic field, it puts a force on the wire. This is known as the motor effect. To determine the direction of the force you use...

Quantum Numbers, Atomic Orbitals, and Electron Configurations
Orbitals! Oh no. They're so weird. Don't worry, nobody understands these in first-year chemistry. You just pretend to, and then in second-year you learn them a little better, the following year a little better, and once you have a PhD...

Is Spin Angular Momentum afterall?
On why I was very wrong. In my previous video, I said that spin isnt very linked to angular momentum at all- but in fact, theres a key property of angular momentum that spin has, suggesting they are linked after all. Book recommendation:...
