electric displacement, dielectric displacement, dielectric flux density, electric displacement density, electric flux density, electric induction
The electric field intensity multiplied by the permittivity (measure of the ability of a nonconducting material to retain electric energy when placed in an electric field) or the property of a dielectric medium which determines the forces that electric charges placed in the medium exert on each other.
electric line of force, electric flux line, electric flux, electrostatic flux
1. An imaginary line in which each segment of the line is parallel to the direction of the electric field or the direction of the electric displacement at that point, and the density of the collection of the line is relative to the electric field or the electrical displacement.
2. The electric lines of force that make up an electric field or region.
3. The integral over a surface of the component of the electric displacement perpendicular to the surface and equal to the number of electric lines of forces crossing the surface.
The density of radiation falling on or received by a surface or body.
flux density, flux displacement
1. The amount of a given type of radiation that crosses a specified area within a specified period; such as, the number of photons passing through one square centimeter of a target in one second.
2. The electric flux passing through a surface, divided by the area of the surface.
3. A vector field that represents the differential flux of field lines per unit area.
In metallurgy, a quality rating of silica refractories (heat-resistant materials, usually nonmetallic, which are used for furnace linings, etc.)
A detector that produces an electric signal with magnitude and phase proportional to the magnetic field along its axis; used to demonstrate the direction of the terrestrial magnetic field.
In induction heating, an equipment component that guides the magnetic flux to preferred locations.
Any magnetic flux used in electromagnetism that does not pass through the part of a magnetic circuit where it is needed.
Te passage of magnetic flux that is produced in electromagnetism by one component or circuit through another component or closed circuit, creating a magnetic interaction between the two.
flux of energy, energy flux
A quantity measuring the rate of energy flow; the energy per unit time per unit area traveling across a surface element that is perpendicular to the energy flow.
In electromagnetism, a path in physical space that a magnetic flux line follows.
In materials science, the prevention of flux movement and resulting quenching of a superconducter by the use of ultra-thin filamentary composites that lower the risk of flux jump.
A cryogenic generator capable of hanging small inputs of alternating current into large outputs of direct current.
flux refraction (s) (noun)
, flux refractions (pl)
An abrupt change in direction of magnetic flux lines at the interface between two materials having different magnetic permeabilities.
A sensor that measures the flow of energy as a fluid.
Astrophysics, the unit of flux density or "brightness" used in radio astronomy.
Welding using a filler metal that contains a flux in its core.
A process by which radiation flux density is tracked within a reactor or other radiation source.
gamma flux density
The number of gamma rays passing through a unit area in a unit of time.
Diarrhea accompanying severe liver disease.
irradiance, radiant flux density
1. A radiometric term for the rate at which radiant energy is transferred across a unit area of a surface, commonly measured in watts per square meter.
2. A radiometric term for the rate at which radiant energy in a radiation field is transferred across a unit area of a surface (real or imaginary) in a hemisphere of directions.
In general, irradiance depends on the orientation of a surface. The radiant energy may be confined to a narrow range of frequencies (spectral or monochromatic irradiance which is characterized by a single frequency) or integrated over a broad range of frequencies.
luminous flux (s) (noun) (usually not plural)
The rate of flow of radiant energy, expressed by brightness that is emitted in a unit of solid angles by a uniform point source with intensities of one candela or the base unit of beaming intensity or the power emitted by a source of illumination: Dr. Young and the scientists measured the luminous flux using the latest equipment designed to indicate in lumen the rate or speed of light transmission.
The blood and fluid of menstruation.
The amount of substance excreted in urine divided by time, expressed in nanomoles (a unit of amount of substance equal to 10-9
[one billionth] moles per second).
Moles refer to the actual number of atoms or molecules in an object.
