Phenomenon related to the propagation of electric and magnetic energy. Defined by frequency in the Electromagnetic Spectrum. Electric and Magnetic energy is coupled. Meaning you cannot have one without the other. Described as Electromagnetic fields.
Electromagnetic wave is energy radiation that consists of electric and magnetic fields perpendicular to each other. Electromagnetic wave is produced by electric charge acceleration or magnetic field variation. In vacuum, electromagnetic wave travels at the speed of light (notation: ), that is 300,000 kilometers/second or 186,000 miles/second. Electromagnetic spectrum encompasses all types of electromagnetic radiation. In general, in the order from the lowest to the highest frequency or from the longest to the shortest wavelength, it can be classified to: - radio wave (ELF, SLF, ULF, VLF, LF, MF, HF, VHF, UHF, SHF, EHF) - microwave (SHF, EHF) - infrared light (300 GHz - 400 THz) - visible light ( 400 THz) - ultraviolet light - x-rays - gamma rays Electromagnetic radiation is described in two equations below: = λf where : the speed of light, : wavelength, : frequency = hf where : photon energy, : Planck's constant, : frequency The first is for electromagnetic radiation as a wave, and the second as particles. EM is the shorthand of electromagnetic.
Magnetic ( generator) production of electricity.
The combined electric and magnetic field caused by the flow of electrons in a conductor.
pertaining to or exhibiting magnetism produced by electric charge in motion; "electromagnetic energy"
Mineral-hunting technique the equipment used introduces electric currents from above the surface, or in the air, into the earth. The electrical activity is measured during and after the currents have passed through rocks deposits. (See "Anomaly".)
flow meter that uses the same principle as an electric generator in that a voltage is induced when a conductor is moved in a magnetic field, the fluid is the conductor and meter body provides the magnetic field and the electrodes.
Having both an electrical and a magnetic character or property.
Of, relating to, or produced by electromagnetism, magnetism developed by a current of electricity.
Radiation (EMR) Energy propagated through space or through material media in the form of an advancing interaction between electrical and magnetic fields.
The interaction between electric and magnetic fields.
relating to magnetism which is developed by the passage of an electric current
Relating to the interplay between electric and magnetic fields.
Pertaining to the combined electric and Magnetic Field s associated with movements of electrons through conductors.
Having both magnetic and electrical properties.
EM] Comprised of a time-varying electrical and magnetic field. Radio waves are common electromagnetic fields. In geophysics, an electromagnetic system is one which transmits a time-varying primary field to induce eddy currents in the ground, and then measures the secondary field emitted by those eddy currents.
A magnetic field cause by an electric current. Power lines cause electromagnetic fields that can interfere with nearby data cables.
(adj) Describes magnetism developed by a current of electricity.
Energy carried by electric and magnetic waves.
Referring to the combined electric and magnetic fields caused by electron motion through conductors.
Very efficient means of controlling electromechanical display characters. Each moving part of the character contains a magnet, that upon command receives an electrical charge that either attracts or repels the magnet to or from its base, causing it to move.
Pertaining to magnetic force thatâ€(tm)s created by electricity. Some nailers use electromagnetic energy to drive the hammer.
Objects made magnetic by an electric current.
The term describing the relationship between electricity and magnetism. A quality that combines both magnetic and electric properties.
Radiation A kind of radiation including visible light, radio waves, infrared rays, gamma rays and x-rays in which electric and magnetic field vary simultaneously.
