Electromagnetic Field (EMF) as a Measure for Infrared
Infrared is a form of electromagnetic radiation (EMR). EMR, as a current, is surrounded by an electromagnetic field (EMF). For example, lightning is a current between the sky and the ground, or wherever it travels, and an EMF encircles it as it travels. Infrared waves of light energy is surrounded by EMF as well. Therefore, EMF levels can indicate the presence of infrared radiation (IR).
