Stern-Gerlach Experiment, In A Simple Physics Model

A  Physics  Model  The  Simple  Model  The  Simple  Universe 

The animation shows the inhomogeneous magnetic field of the Stern-Gerlach apparatus, changing the electron's random vertical orientation of the plane of its torus ring, to align with the vertical plane

As a note, a suggestion is required as to what a magnetic field is, in this physics model

As a suggestion, perhaps a magnetic field is an overall neutral electric field that, from each atomic point source of the electric field, the majority of the short positive electric field particles move in one direction, and the majority of the short negative electric field particles move in another direction, the two directions being at an angle to each other

For reference, here is a YouTube video (2019) that discusses the behaviour of the silver atoms / electrons as they pass through the inhomogeneous magnetic field of the Stern-Gerlach apparatus YouTube channel Ryan Steinbach

Transcript of the discussion between 2:30 and 2:50

The inhomogeneous magnetic field, forces the electron's spin to take an orientation, either in line with the inhomogeneous magnetic field, or in the opposite direction

If the basis state is close to up, it is very unlikely to change the direction to down, however it may still do so
