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. EMFs are typically characterized by wavelength or frequency into one of two radioactive categories:
Non-ionizing: low-level radiation which is generally perceived as harmless to humans Ionizing: high-level radiation which has the potential for cellular and DNA damage
EMF's are characterized by frequency or wavelength into one of two radioactive category : non-ionizing and ionizing.electric magnetic field is not perceptible in energy area.It affect behavior of charged objects in the vicinity of the field.
