We reported the effects of magnetic fields on polymorphism for glycine crystal made by liquid-liquid interfacial precipitation (LLIP) method under high magnetic field. The XRD pattern for glycine crystal made by several magnetic fields was measured to assign crystal structure and the ratio of polymorphism was evaluated from the ratio XRD peak height. In this study, the mechanism was investigated the effects of magnetic fields on polymorphism for glycine crystal by changing magnetic flux and gradient of magnetic fields under vertical magnetic fields. As the results, the ratio of unstable crystal was increased with increasing negative magnetic force fields.
