Electromagnetic energy is the energy carried by electromagnetic waves, which are ripples of electric and magnetic fields moving through space. It includes everything from the radio signals streaming music to your phone to the X-rays taken at a dentist’s office to the visible light you’re reading by right now.
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 theory is based on four fundamental equations, known as Maxwell’s equations, that relate the electric and…

In physics, electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields. The electromagnetic force is one of the four fundamental forces of nature. [1] It is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electrostatics and magnetism, which are distinct but closely ...
What is Electromagnetic energy? 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. A radio detects a different portion of the spectrum, and an x-ray machine uses yet another portion. NASA's scientific instruments use the full range of ...
Electromagnetic waves combine an electrical field (in yellow) and a magnetic field (in blue). The result is a type of radiation that travels infinite distances though the universe (green arrow).
