Electromagnetic Properties of Bone Electromagnetic Properties of Bone Bone is a vascular, constantly remodeling, mineralized connective tissue despite its stonelike appearance. The amount of deformation is dependent on the bending moment and axial loads placed on the vertebrae.
Abnormal posture causes asymmetrical axial loading.
When axial loads are not parallel with the material direction, the asymmetrical forces cause polarization and stress-generated potentials. A moving current is formed which results in an electrical magnetic field. In 1896 the relationship of bone growth to pressure was defined as Wolff's Law. The form of a bone being given, the bone elements place or displace themselves in the direction of the functional pressure and increase of decrease their mass to reflect the amount of pressure. This law states that bone will remodel to stress placed upon it.
