  Abstract: An experiment studying the physics underlying the Zeeman effect and Paschen-Back effect is developed for an advanced physics laboratory. We have improved upon the standard Zeeman effect experiment by eliminating the Fabry-Perot etalon, so that virtually any emission line in the visible spectrum can be analyzed. Emitted light from a ~1T magnet is analyzed by a Czerny-Turner spectrograph equipped with a small-pixel imaging CCD. The experiment was taught as part of the Principles of Experimental Physics course at Northeastern University to a combination of graduate/undergrad students. Zeeman’s original sodium experiment is recreated, and the splitting of argon and helium lines is measured as a function of field strength. The students analyze the proportionality of the splitting magnitude to both the B-field strength and lambda squared. The Bohr magneton is calculated and compared to theory. Student feedback is positive, citing the ability to experimentally witness a quantum mechanical effect.
