Fig. 1.2. Organization of bioelectromagnetism into its subdivisions. It is first divided horizontally to:
B) bioelectromagnetism (biomagnetism), and
Then the division is made vertically to:
I) measurement of fields,
II) stimulation and magnetization, and
III) measurement of intrinsic electric and magnetic properties of tissue.
The horizontal divisions are tied together by Maxwell's equations and the vertical divisions by the principle of reciprocity.
