Obviously, in static magnetic fields the isotropic distribution of cortical electrical charge movements becomes an anisotropic state. By this effect we have the phenomenon that the spontaneous EEG is triggered by external Zeitgeber like electrical stimuli of N. medianus or internally by the ECG. This orientation of charge transports leads to an additional varying magnetic field which induces currents in coils placed at the same positions like EEG-electrodes.
显然，在静磁场中，皮质电荷运动的各向同性分布会变为各向异性状态。通过这种效应，我们会观察到如下现象：自发脑电图是由诸如正中神经电刺激等外部授时因子触发的，或者是由心电图在体内触发的。这种电荷传输的定向会导致一个额外的变化磁场，该磁场会在与脑电图电极位置相同处放置的线圈中感应出电流。
