[Biological effects of the action of permanent magnetic ...

The data on biologic effect of constant magnetic fields (CMF) of various intensity were presented. It was shown that animals (white rats) exposed to CMF of 1600-400 kA/m experienced moderately distinct functional changes, manifested by raising excitability of the CNS spinal sections, hypothermic reactions and variations in some blood indices.
