Electromagnetic fields are areas of energy that are associated with the movement of electrically charged particles. These fields can be produced by a variety of sources, including electrical currents, magnetic materials, and electromagnetic radiation such as light. Research in the field of electromagnetic fields includes studying their effects on living organisms, developing technologies that utilize electromagnetic fields (such as wireless communication and medical imaging), and understanding the fundamental physics behind their behavior. This research is important for a wide range of applications, from medical treatments to telecommunications to environmental protection.
