Quantum Spin (4) - Classical Dynamics in Magnetic Field

Описание к видео Quantum Spin (4) - Classical Dynamics in Magnetic Field

[High School Level] - (MISTAKE: From 43:09 - 55:08 all of the cosines should be sines. Thank you to N.H for pointing this out!) I did not expect this video to get so long! In this video I go through what happens to a spinning electron in classical physics. I explain Larmor Precession and derive the formula for the torque and potential energy of an electron in an external magnetic field. I then use the classical formula for energy to motivate Schrödinger's equation for a spin 1/2 particle. I then give a little discussion on the g-factor and quantum field theory.
