提出了弱磁场与生物系统共振相互作用的物理机制。Ca2+结合蛋白内的离子由带电振荡器近似表示。当施加静磁场和交变磁场的组合时，离子跃迁在不同振动能级之间的概率发生了变化。这反过来又影响离子与周围配体的相互作用。当交变场的频率等于该离子的回旋加速器频率或等于其某些谐波或次谐波时，该效应达到最大。生物系统对磁场产生共振反应。提出的理论允许对实验观察到的效应的主要特征进行定量解释。
A physical mechanism is suggested for a resonant interaction of weak magnetic fields with biological systems. An ion inside a Ca2+ -binding protein is approximated by a charged oscillator. A shift in the probability of ion transition between different vibrational energy levels occurs when a combination of static and alternating magnetic fields is applied. This in turn affects the interaction of the ion with the surrounding ligands. The effect reaches its maximum when the frequency of the alternating field is equal to the cyclotron frequency of this ion or to some of its harmonics or sub-harmonics. A resonant response of the biosystem to the magnetic field results. The proposed theory permits a quantitative explanation for the main characteristics of experimentally observed effects.
