What are the applications of remote sensing using electromagnetic radiation?

Electric fields are present when an electrical appliance is plugged in even when turned off. Electric fields diminish rapidly with distance from the source. A half century ago, Ad Kalmijn proved that sharks can sense electromagnetic fields. His work is still reshaping our understanding of ocean ecosystems. Scientists and oversight agencies generally agree that low-frequency EMFs pose little danger to human health. Jan 29, 2023 ... Electromagnetic radiation is a form of energy that is produced by oscillating electric and magnetic disturbance, or by the movement of electrically charged ... 1.1 What are electromagnetic fields? ... Electromagnetic fields are a combination of invisible electric and magnetic fields of force. They are generated by ...
