Clinically, biomagnetic therapy is reported to lessen the discomfort arising from a variety of degenerative joint conditions, such as osteoarthritis and aid in the recovery of joint and tendon injury. However, these claims are not paired with in situ or laboratory examinations of the affected anatomy following therapy.

Biomagnetic therapy is a proposed approach to analgesia that utilizes the non-invasive application of static magnets to create an electromagnetic field to areas of musculoskeletal damage or perceived discomfort.

Biomagnetism is the phenomenon of magnetic fields produced by living organisms; it is a subset of bioelectromagnetism. In contrast, organisms' use of magnetism in navigation is magnetoception and the study of the magnetic fields' effects on organisms is magnetobiology.

Biomagnetism is the measurement of the weak magnetic fields produced by nerves and muscle. The magnetic field of the heart—the magnetocardiogram (MCG)—is the largest biomagnetic signal generated by the body and was the first measured.
