What Happens in a Uniform Magnetic Field: The Stern-Gerlach Experiment

[nirmali]

What effect the magnetic field would have produced had it been uniform?

The beam wouldn't split!

But what if we were to answer it mathematically?

 

[ShayanJ]

We would say the force on the dipoles is proportional to the gradient of the field and so a uniform field doesn't exert a force on the dipoles.
