What does EMF mean?

Extremely low frequency (ELF) fields includes alternating current (AC) fields and other electromagnetic, non-ionizing radiation from 1 Hz to 300 Hz . ELF fields at 60 Hz are produced by power lines, electrical wiring, and electrical equipment.

EMF is a combination of electrical and magnetic fields . The strength of an EMF is directly related to the amount of electricity in use (the current) and to the electrical potential (the voltage) in the electric circuit. That means the more current or the higher the voltage, the greater the EMF which could be generated.

Electric and magnetic fields (EMFs) are invisible areas of energy, often referred to as Radiation, that are associated with the use of electrical power and various forms of natural and man-made lighting.
