Electromagnetic field influences the behavior of objects in the vicinity of an electromagnetic field. The Electromagnetic waves that carry electromagnetic energy is a family of waves based on the frequency and wavelength (Tom and Heather 34). Arranged in order of increasing frequency then we have Gamma rays, ultraviolet radiation, X-rays, Visible light, Microwaves Infrared, and Radio waves. Gamma rays have the highest frequency hence a high energy while the Radio waves have the lowest frequency and therefore have less energy.
Electromagnetic energy can be stored in electrical devices such as the capacitors and Inductors. For an electric field, the total energy density which is given by energy stored per unit volume can be determined to be . Where the symbols assume their scientific meaning, this relation is useful in the evaluation of the total energy stored in a capacitor. An inductor is a coil of electrical wire with parameters that enable it to store energy in the form of the magnetic field (David, 1989). The magnetic field energy density is given by. This energy density is useful in the determination of energy stored in the Inductor. Both the electric and magnetic fields play important roles in energy transport as described by the pointing vector (Mats and Jonsson 23). It is however important to notice that the energy associated with magnetic and electric fields is equal and therefore the use of one the equation above can be used to represent the other. It is also important to realize that for an electromagnetic wave with particular energy, the electric field is directly proportional to the energy of “the magnetic field with a constant of proportionality equal to the speed of light” (Mats and Jonsson 30)
