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 ...
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.
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).
Electromagnetic Theory covers the basic principles of electromagnetism: experimental basis, electrostatics, magnetic fields of steady currents, motional e.m.f. and electromagnetic induction, Maxwell's equations, propagation and radiation of electromagnetic waves, electric and magnetic properties of matter, and conservation laws. This is a graduate level subject which uses appropriate ...
