This paper reports the investigation on special noise in an intracavity He-Ne laser. It is induced by a spatial magnetic field which consists mainly of earth magnet. Based on the theory of Zeeman laser and dispersion character of laser medium, the production mechanism and the regularity of magnetic induced beat noise are explained. Finally some methods for eliminating this noise are suggested.
