The main problem in the total problem of biological effects of natural geomagnetic disturbances is a deficit which riches 5-7 orders of magnitude between modelled current and fields in biological media by slow and weak fields caused by geomagnetic disturbances, including the most severe storms, and reported correlations between biological objects and geomagnetic disturbances. Several mechanisms, such as super-paramagnetic properties of specific proteins, can partly compensate this deficit. This allows to discriminate between studies, based on false correlations, and the effects, which may be related to geomagnetic disturbances. In the present review, we give a summary of biological phenomena related to magnetic field variations of “geophysical” amplitudes and frequencies. We attempt to classify reported biological studies in accordance with possible physical mechanisms.
