Understanding Electric and Magnetic Fields
Electric and magnetic fields are invisible areas of energy, or radiation, that are produced by electricity. An electric field is created by voltage, which is the pressure that pushes electrons through a wire. The strength of the electric field increases with higher voltage. Magnetic fields, on the other hand, result from the flow of current through wires or electrical devices and increase in strength as the current increases. Electric fields are present whether a device is turned on or not, while magnetic fields are produced only when current is flowing. When electric and magnetic fields are combined, they form electromagnetic fields (EMFs).
EMFs can be categorized as either non-ionizing or ionizing radiation, depending on their frequency. Non-ionizing radiation, which includes low to mid-frequency EMFs, is not known to directly damage DNA or cells. Ionizing radiation, on the other hand, includes high-frequency EMFs like X-rays and gamma rays, which have the potential to harm cells and DNA.
