The Definition of Bioelectromagnetism

Bioelectromagnetism refers to the electrical, magnetic or electromagnetic fields produced by living cells, tissues or organisms. Examples include the cell membrane potential and the electric currents that flow in nerves and muscles, as a result of action potentials.

Biological cells use bioelectricity to store metabolic energy, to do work or trigger internal changes, and to signal one another. Bioelectromagnetism is the electric current produced by action potentials along with the magnetic fields they generate through the phenomenon of electromagnetism.

The theory is an aspect of all living things, including all plants and animals. Some animals have acute bioelectric sensors, and others, such as migratory birds, are believed to navigate in part by orienteering with respect to the Earth's magnetic field. Other animals, such as the electric eel, are able to generate large electric fields outside their bodies.

Moreover, bioelectromagnetism involves the interaction of ions. There are multiple categories of Bioelectromagnetism such as brainwaves, which neurophysiology studies, where bioelectromagnetic fluctuations of voltage between parts of the cerebral cortex are detectable.




The Definition of Bioelectromagnetics

Bioelectromagnetics is the study of how electromagnetic fields interact with and influence biological processes. Common areas of investigation include the mechanism of animal migration and navigation using the geomagnetic field, studying the potential effects of man-made sources of electromagnetic fields, such as those produced by the power distribution system and mobile phones, and developing new therapies to treat various conditions.
