While living beings have always been exposed to natural electromagnetic fields, the growing sources, applications, and impact of human-made electric and magnetic fields (EMFs) on humans and the ...

Electric and magnetic fields occur naturally and also come from human-made sources. Scientists and oversight agencies generally agree that low-frequency EMFs pose little danger to human health.

The study of electromagnetism deals with how electrically charged particles interact with each other and with magnetic fields. Maxwell developed a set of formulas, called Maxwell's equations ...
