An electric field occurs whenever charges are present; a magnetic field occurs whenever charges are in motion, as in the case of an electric current. EMFs are emitted by all wires and machines that carry current, including home wiring and all electric-powered home appliances, from coffeemakers to VCRs, as well as power lines and electrical substations. A number of respected scientists contend that EMFs are linked to the development of cancer. (Marinelli and Bierman-Lytle, 1995, pp.245-246)
A field of force associated with a moving electric charge and consisting of electric and magnetic fields that are generated at right angles to each other.
The field of force around electric charges or currents. If the source of the field oscillates in time, the disturbance will propagate outward at the speed of light. This radiating field is described as radio waves, microwaves, infrared radiation, light, ultraviolet light, and so on, depending on the rate at which it is oscillating.
field created by a combination of electric and magnetic energy that emits from radio and light waves to gamma and cosmic rays
ih lehk tro maeg neh tihk fild] A region of space in which electrical and magnetic forces exist and are described by a field. It has two components, magnetic, and electric. These can be at widely varying levels relative to each other. Natural phenomena involving electomagnetic fields include light, radio waves, TV signals. The image below represents the electromagnetic field lines emanating from a rotating planet or star.
The coupled electric and magnetic fields that are generated by time and varying currents and accelerated charges.
an electric field and a magnetic field together. Since electric and magnetic fields are intimately linked to one another it makes sense to have a name which indicates both together. Electromagnetic waves, including light, consist of electromagnetic fields.
waves described by a electrical component and a magnetic component both of which change in space and time.
A rapidly moving electric field and its associated moving magnetic field, located at right angles both to the electric lines of force and to their direction of motion.
Field of the electromagnetic force, consisting of electric and magnetic lines of force at each point in space.
a force associated with electric charge in motion having both magnetic and electrical components resulting in a definite amount of electromagnetic energy
a magnetic field created by electricity
an association of an electric field and a magnetic field that vary in time and propagate together in space
a region around a magnet where the force of that magnet and the force of electricity can be felt
a region through which a force produced by
the regions of space near electric currents, magnets, broadcasting antennas etc., regions in which electric and magnetic forces may act. Generally the EM field is regarded as a modification of space itself, enabling it to store and transmit energy.
Electric and magnetic forces that exist in a physical volume.
The electrical and magnetic fields produced by any device operating with electricity.
An electromagnetic field is the propagation in space of time-varying electric fields and magnetic fields.
The electrical and magnetic fields created by the presence or flow of electricity in an electrical conductor or electricity consuming appliance or motor.
invisible lines of force that are the result of the use of electricity, such as anything plugged into an outlet or operated by a battery.
The field of force associated with electric charge in motion, having both electric and magnetic components and containing a definite amount of electromagnetic energy; believed to be generated when spirits manifest.
Invisible lines of force that are created from the flow of electricity, such as when using an electrical device that is plugged into an outlet or operated by a battery.
The field of influence produced around a conductor by the current flowing through it. These are sometimes referred to as flux lines in the design of a sealing head.
Electric and magnetic force field that surrounds a moving electric charge.
A magnetic field created through the conductive material by electric force
An invisible force extending from top and bottom of the searchcoil created by the flow of alternating oscillator frequency current around the transmit winding. See also Detection Pattern.
A field propagated by a combination of electric and magnetic energy which radiates from radio and light waves to gamma and cosmic rays. It is believed that when spirits manifest, they create an electromagnetic field.
The combination of an electric (E) field and a magnetic (H) field.
The field of force that an electrical current produces around the conductor through which it flows.
A field that is created when energy from a power source such as a battery is applied to a circuit, making the electrons flow through a conductor, a new type of field is developed around the wire.(Basic Science/Electricity/electrostaticfield.htm)
A formation of a group of magnetic lines of force surrounding a conductor created by electrical current in the conductor.
The electromagnetic field is a physical field that is produced by electrically charged objects and which affects the behaviour of charged objects in the vicinity of the field. The electromagnetic field extends indefinitely throughout space and describes the electromagnetic interaction, one of the four fundamental forces of nature. The field can be viewed as the combination of an electric field and a magnetic field.
