what is electromagnetism
Basics of Electromagnetism. by Ron Kurtus (revised 17 December 2012) Electromagnetism has two meanings, depending on whether viewed at the subatomic level or on an everyday scale. At the subatomic level, electromagnetism is defined as the force between electrically charged particles. It is considered one of the fundamental interactions of matter. Oscillating electrical charges result in electromagnetic waves. On a larger scale, electromagnetism is the creation of a magnetic field from the movement of electrical charges.
