Abstract
In this experiment the gyromagnetic ratio of a sample of very pure iron was determined. The sample was wound with a magnetizing coil and supported as a torsional pendulum in an evacuated space almost completely free of residual magnetic fields. Changes in pendulum amplitude were brought about by repeated and synchronized reversals of the magnetizing current. These changes were measured along with corresponding changes in magnetic moment of the sample. The average value obtained for the gyromagnetic ratio was 1.0278±0.0014 times the mass-to-charge ratio of the electron.Keywords
