Very weak magnetic fields have been shown to be associated with the human brain and heart. These fields, apparently physiologic, are about one million times weaker than the geomagnetic, the earth's steady magnetic field, which measures about 0.5 gauss. Fields of about 10(-8) gauss are perhaps correlable to genomic masses and associated structures like peptide hormone trophic factors. The connection between genes and magnetic fields is made from a new form of resonance called Jacobson Resonance. Jacobson Resonance, represented by the equation mc2 = Bvl coulomb, is explained. Indeed, we may view the possibility of linking human electromagnetic interactions with mechanical vibrations of the crystalline lattices of genes and associated critical molecules like growth factors. As these fields are applied to the equations for solenoidal models, currents of about a microampere are derived; in perfect accord with recent clinical data indicating the therapeutic efficacy of weak currents in repair and growth of soft tissue, bone and nerve. The mechanism of reorientation of spin angular momentum of electrons and protons influencing molecular magnetic domains to bring about 'particle jumps' is presented so that a clinical picture results. The clinical picture is that of an organism placed at right angles to flux lines in the midst of a solenoid immersed in water exposed then to exogenously applied resonant physiologic magnetic fields. They may convert malalligned atomic lattices of oncogenes and associated particles to homologous normal structures which may promulgate an adjustment to physiological homeostasis.
