EM (Electromagnetic) fields

Electromagnetic (EM) fields are areas of energy generated by electric and magnetic forces, which are interconnected. They surround us in many forms, such as the signals that enable your phone to connect or the light from the sun. An electric field occurs around charged particles, while a magnetic field is created by moving charges or currents. These fields can exist together and interact, forming the foundation of electromagnetic waves, including radio waves, microwaves, visible light, and more. EM fields are essential for wireless communication, electrical power, and various technologies integral to modern life.
