Biological effects of magnetic fields generated with CoSm magnets

Experiments were conducted to determine whether any observable short-term biological effects were caused by a static magnetic field created with CoSm magnets similar to those used in the elbow prosthesis described on pages 69-80. Tissue culture studies of several cell lines showed no obvious effects on cell growth rate, morphology, or the ability to grow and remain confluent; and no deleterious effects of the magnetic field were evident as a result of an in-vivo study of wound and bone healing in rats. Long-term effects, if any, have yet to be determined.
