This paper studies the effect of the synergism of magnetic field and solvents on the crystallization of glutamic acid and the effects of magnetic field on surface tension and conductivity of glutamic acid supersaturated solution. The mechanism of the encouragement of magnetic field on the crystallization is discussed too, thus a new method to produce the crystal seeds by the synergism is presented. It is shown that the speed of crystallization of glutamic acid is hastened by magnetic field. The crystal seeds got by the method have the advantage of well_distributed crystal size and integrated, purity crystallization.
