Situation where increasing concentrations of a reactant (or transport material) fail to increase the reaction rate.
(1) The condition existing in any circuit in which an increase in the input signal produces no further change in the output. (2) The operating point of a vacuum tube or transistor at which a further increase in grid or base current no longer produces an increase in plate or collector current. (3) In a magnetic core, the condition in which a magnetic material has reached a maximum flux density and the permeability has decreased to a value of (approximately) 1.
The condition where energy flux exceeds the sensitivity range of a detector.
The distortion caused by magnetic recording media being unable to store as much high frequency information as low frequency information.
Magnetic saturation exists when an increase of magnetization applied to a reed contact does not increase the magnetic flux through.
Condition in which a further increase in an independent parameter produces no increase in the dependent parameter.
a condition in which a quantity no longer responds to some external influence
It is a condition in a magnetic core when it can no longer sustain a magnetic flux density. It runs out of room. The result is the effective permeability of the core can quickly change from very high to near that of air as the flux density increases. Different materials and shapes can make the transition softer but it happens to all core materials. Similar to a sponge's ability to absorb water, once it has absorbed all it can any more water will simply roll off.
The state where an increase in magnetizing force produces no further increase in magnetic induction in a magnetic material.
The degree of magnetization where a further increase in magnetic field strength produces a decrease in permeability of a material.
A condition under which induction of a ferromagnetic material has reach its maximum value with the increase of applied magnetizing force. All elementary magnetic moments have become oriented in one direction at the saturation status.
The point at which the tape is fully magnetized and will accept no more magnetization.
A condition where the increase in applied external field yields no increase in induction. When this condition is met, all of the elementary magnetic moments have the same alignment. This condition is important in permanent magnet alloys and in Ferromagnetic alloys. Magnet alloys must always be magnetized to saturation. The magnet may not be used at this level, but before conditioning and stabilization the magnet must always first be magnetized to saturation. Usually saturation should not be exceeded in Ferromagnetic alloys which comprise the yoke or return path elements of a magnetic circuit. If ferromagnetic elements are saturat ed there will be flux leakage in the system and a redesign should be considered. search coil is a coiled conductor, usually of known area and number of turns, that is used with a flux meter to measure the change of flux linkage with the coil.
A magnetic-recording term used to describe a condition whereby recording tape or tape heads are carrying all the signals that they can handle. Any additional input results in no additional storage or recording output levels.
The condition under which all elementary magnetic moments have become oriented in one direction. A ferromagnetic material is saturated when an increase in the applied magnetizing force produces no increase in induction. Saturation flux densities for steels are in the range of 16,000 to 20,000 Gauss.
A picture's saturation, or density, refers to how much light is present.
A condition in a magnetic material in which an increase in (b ) will no longer produce an appreciable increase in (H ).
The condition of a tape coating or head that has accepted its maximum degree of magnetisation, or of an amplifier that is at the point of clipping. Distortion increases sharply as signal level approaches the point of saturation.
Condition in which a surface becomes completely covered with craters, such that the addition of new craters does not increase the overall crater density.
This is a condition where all magnetic moments have become oriented in one direction.
Condition in which a further increase in one variable produces no further increase in the resultant effect. In a bipolar junction transistor, the condition when the emitter to collector voltage is less than the emitter to base voltage. This condition puts forward bias on the base to collector junction.
For magnetic materials, saturation is the state when the material cannot absorb a stronger magnetic field, such that an increase of magnetization force produces no significant change in magnetic flux density. The relation between the magnetic field H and the magnetic flux density B is expressed in terms of the magnetic permeability μ : B=\mu H. The permeability of many materials is not constant, but depends on H.
