Biomagnetics

The areas where life sciences and magnetism overlap are reviewed. Direct interactions of magnetic fields on living bodies are described. The interactions of time-varying magnetic fields most probably act through the induced electric currents. The actions of homogeneous and inhomogeneous fields are considered and samples given. Uses of magnetic fields due to currents in living bodies are described, as well as some of the devices and methods through which ferromagnetic materials are artificially introduced into the body.
