Small White Board Question: Magnetic Moment & Stern-Gerlach Experiments

Quantum Fundamentals 2021
Students consider the relation (1) between the angular momentum and magnetic moment for a current loop and (2) the force on a magnetic moment in an inhomogeneous magnetic field. Students make a (classical) prediction of the outcome of a Stern-Gerlach experiment.
What students learn
  • Spin and magnetic moment are related.
  • Magnetic moments experience a force from an inhomogeneous magnetic field
  • Classically, you'd expect a continuous smear in a Stern-Gerlach experiment, but what you get is two dots.
