A Dynamic Model of Magnetic Resonance Phenomena

Frank Verbrugge

Abstract

A dynamic model to illustrate atomic and nuclear magnetic phenomena is described. An airdriven spinning magnetic dipole placed in a magnetic field exhibits a Larmor precession whose dependence on magnetic and gravitational parameters can be demonstrated. An ac magnetic field of variable frequency permits a visual demonstration of magnetic resonance. Data obtained from the precession experiments can be used for a precise determination of the earth's magnetic field.
