磁取向是对生物系统的明显磁场效应。由于大多数生物分子由蛋白质和脂质等抗磁元素组成，因此由于分子的净抗磁各向异性，它们通过磁场定向。在公牛精子、其头部和草履虫纤毛中发现了相当大的磁性取向，并且通过光透射和显微镜观察评估了这些材料的有序参数。它们通过磁取向理论和抗磁各向异性模型进行分析。
The magnetic orientation is a clear magnetic field effect on biological systems. Since most of the biological molecules are composed of diamagnetic elements such as proteins and lipids, they are oriented by the magnetic field as a result of a net diamagnetic anisotropy of the molecule. A considerable magnetic orientation is found in bull sperms, their head parts and paramecium cilia and the order parameter of these materials are evaluated both by the light transmission and the microscopic observation. They are analyzed by the theory of the magnetic orientation with a diamagnetic anisotropy model.
