Stern Gerlach Experiment

  1. Dec 23, 2013 #1
    I'm confused.So a dipole needs a nonuniform field for the net force to not equal zero, cool.

    My question is how do they go from
    F = -∇(μ * B) = ((μ_z)(dB/dz))*(z unit vector)
    how come the gradient has no x or y parts?

    ... because they [messrs Stern and Gerlach] set up the apparatus that way.
    The label "z" for the orientation is arbitrary.
