Magnetic Power Generator
Electromagnetic (EM) energy has the structure of a wave. A range of frequencies exist, known as the EM spectrum, that relate electromagnetic waves by energy level and wavelength. Radio waves through which television and radio station broadcast operate are at the lowest end of the spectrum. Microwaves we use to cook with are next, followed by visible light, x-rays and gamma rays.
Anything that emits energy is generating electromagnetic energy. Whether a campfire, a light bulb, a laptop or a nuclear reaction, all act as generators of EM energy.
Chemical reactions are a key source of EM radiation. In wood, or other substances, when heat is applied to burn the object, an change of state occurs at the molecular level as the substance releases an amount of energy as an EM wave. Similarly, an intense chemical reaction occurs in radioactive substances that power nuclear reactors, giving off heat to power an electric plant as well as other harmful radiation
The chemical process occurring in the sun are a much grander example of that which occurs in a fire. At much higher higher temperatures and with additional elements involved, more types of EM radiation are produced. Stars are the largest know forms of EM generators.
Electromagnetic pulses (EMPs) are produced when short bursts of intense EM waves are released at once. These have been used in for kidney stones and other medical conditions. Care must be take around these devices, as they can cause damage to sensitive electronic equipment.
It's hard to imagine a world in which we as humans did not utilize electromagnetic energy. Life depends on electromagnetic energy, and it's certain that with out naturally occurring electromagnetic energy generators it would come to an abrupt end.
