Electromagnetic Field. An electromagnetic field is referred as a physical field of objects that are electrically charged. It is one among the four fundamental forces of nature, other includes strong interaction, weak interaction, and gravitation. The electromagnetic field affects the change in the behaviour of charged objects surrounding a. Electromagnetic field, a property of space caused by the motion of an electric charge. A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. An electric field can be produced also by a changing magnetic field Electromagnetic fields (EMFs) are part of the physical electromagnetic spectrum ranging from the extreme low of static magnetic fields to the extreme high of gamma rays. EMFs as discussed here focus on frequencies of 0 Hz-300 GHz, which are part of the spectrum considered to be nonionizing (Table 1) Electric and magnetic fields are invisible areas of energy (also called radiation) that are produced by electricity, which is the movement of electrons, or current, through a wire. An electric field is produced by voltage, which is the pressure used to push the electrons through the wire, much like water being pushed through a pipe An electromagnetic field is a field which possesses magnetic and electrical properties and surrounds objects with an electrical charge. The field also interacts with charged objects within the field. Electromagnetic fields are present on a basic level across the universe, in varying degrees of strength

Characteristics of Electromagnetic Fields . EMF is a combination of electrical and magnetic fields. The strength of an EMF is directly related to the amount of electricity in use (the current) and to the electrical potential (the voltage) in the electric circuit. That means the more current or the higher the voltage, the greater th An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil, spiral or helix.

Electromagnetic pollution (or EMF pollution) is a term given to all the man-made electromagnetic fields (EMFs) of various frequencies, which fills homes, workplaces and public spaces. When something in the environment is called a pollutant, it implies that it is somehow harmful to nature and to human beings Dirty electricity is electromagnetic pollution that has such a high frequency that it literally jumps off the wire and travels through the air, becoming a Radio Frequency field. This happens around 2000 Hz, which means that it vibrates 2000 times, or stops and starts 4000 times per second over a much shorter distance
In this article, we propose a method to reconstruct the total electromagnetic field in an arbitrary two-dimensional scattering environment without any prior knowledge of the incident field or the permittivities of the scatterers. However, we assume that the region between the scatterers is homogeneous and that the approximate geometry describing the environment is known. Our approach uses.
