Abstract
The spin and magnetic moment of the nucleon arise from the quark-gluon constituents and the properties of Quantum Chromodynamics. Over the last decade, the results of spin dependent deep inelastic scattering experiments have indicated that the quark spin contribution is a small fraction of the total spin of the nucleon. This initially surprising result has been interpreted as due to a substantial negative polarization of the strange quark-antiquark sea or as evidence of a sizeable gluon polarization. Further experimental studies are underway to address these issues. The magnetic moment of the nucleon may also contain contributions from strange quarks, and this aspect of nucleon structure is being studied via parity-violating electron scattering. The present status of these experimental efforts and their impact on our knowledge of nucleon structure is discussed.
