Electromagnetic theory is a physics field focusing on electric and magnetic fields' interactions. It shows how charges and currents create forces and electromagnetic waves like light and X-rays, detailing their propagation through space.
Electromagnetic Waves and Telecommunications: Electromagnetic waves, including radio waves, microwaves, and light, are used for communication purposes, including radio broadcasting, television, mobile phones, and wireless internet.
Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. The human eye can only detect only a small portion of this spectrum called visible light.
Electromagnetic waves are the self-propagating, mutual oscillation of electric and magnetic fields. The propagation of electromagnetic energy is often referred to as radiation.

Science Daily: Efficient methods developed to simulate how electromagnetic waves interact with devices
It takes a tremendous amount of computer simulations to create a device like an MRI scanner that can image your brain by detecting electromagnetic waves propagating through tissue. The tricky part is ...
Electromagnetic forces occur between any two charged particles. Electric forces cause an attraction between particles with opposite charges and repulsion between particles with the same charge, while magnetism is an interaction that occurs between charged particles in relative motion.
