What is electromagnetic energy?
Electromagnetic energy consists of waves of electric and magnetic energy radiating through space, and travelling at the speed of light. The area where these waves are found is called an electromagnetic field. The main source of electromagnetic energy is the sun, but man-made sources account for large amounts of the electromagnetic radiation in our day-to-day environment. Items such as hairdryers, electrical ovens, fluorescent lights, microwave ovens, stereos, wireless phones and computers produce electromagnetic fields of varying intensities.
