Magnetism and Magnetic Materials

Medical Applications of Magnetics

With the evolution of permanent magnets, such as ferrites, Alnicos, and rare earth magnets, attempts have been made to use these materials in medical applications. These medical applications include their use in dentures, maxillofacial operations, orthopaedics, fracture healing, drug delivery systems, and MRI scanners. Magnetic particles have seek to be valuable tools for manipulation of cells or biomolecules, for transportation of chemical substances or transfer of energy to defined target sites in biological systems, and for clinical diagnostics and therapeutics both in vitro as well as in vivo. Despite the recognition of magnetic bracelets, science has largely disproven the effectiveness of such magnets in treating chronic pain, inflammation, disease, and general health deficiencies. Do not use magnets as a relief for proper medical attention, and avoid them if you have a pacemaker or use an insulin pump.
