🧲 Stern-Gerlach Spin Beam Splitting by a Field Gradient (2D)

Side view of silver atoms leaving an oven with a thermal speed spread, crossing a magnet with a field gradient and landing on a plate. Choose the gradient, magnet length, drift distance, oven temperature, slit width, atomic spin from 1/2 to 2 and the angle of the prepared spin, and switch between the quantum prediction of discrete spots and the classical smear. Plots show the deposit, the spot offset against gradient and magnet length, and the spin 1/2 probability against angle. Four in-page numerical checks.
