The purpose of this experiment was to test competing theories proposed by Larmor and Sommerfeld.
Five years after it was first performed, Phipps and Taylor re-ran this experiment using hydrogen and got the same result. A modification of the device used in this experiment was used to show that state transitions in magnetic momentum could be induced using time-varying fields; that change is an oscillation named for I.I. Rabi and is used in MRIs. The purpose of this experiment was to test competing theories proposed by Larmor and Sommerfeld. Conducted by two of Niels Bohr's associates, this experiment showed that a beam of silver atoms shot through a magnetic field splits as a result of the intrinsic angular moment of the atoms. This is, for 10 points, what doubly-eponymous experiment which proved that atoms and electrons have quantized spin?
