Magnetic-susceptibility sentence example
Those substances which are attracted, or rather which tend, like iron, to move from weaker to stronger parts of the magnetic field, are termed paramagnetic; those which are repelled, or tend to move from stronger to weaker parts of the field, are termed diamagnetic. Between the ferromagnetics and the paramagnetics there is an enormous gap. The maximum magnetic susceptibility of iron is half a million times greater than that of liquid oxygen, one of the strongest paramagnetic substances known.
The magnetic susceptibility expresses the numerical relation of the magnetization to the magnetizing force.
From the equation K=(µ - I)/47r, it follows that the magnetic susceptibility of a vacuum (where µ = I) is o, that of a diamagnetic substance (where, u I) is positive.
Villari in 1868 that the magnetic susceptibility of an iron wire was increased by stretching when the magnetization was below a certain value, but diminished when that value was exceeded; this phenomenon has been termed by Lord Kelvin, who discovered it independently, the " Villari reversal," the value of the magnetization for which stretching by a given load produces no effect being known as the " Villari critical point " for that load.
Guillaume' the temperature at which the magnetic susceptibility of nickel-steel is recovered is lowered by the presence of chromium; a certain alloy containing chromium was not rendered magnetic even by immersion in liquid air.Advertisement
Rowland,' whose careful experiments led to general recognition of the fact previously ignored by nearly all investigators, that magnetic susceptibility and permeability are by no means constants (at least in the case of the ferromagnetic metals) but functions of the magnetizing force.
Magnetic susceptibility The magnetic susceptibility of a material is its ability to become magnetized by an external magnetic susceptibility The magnetic susceptibility of a material is its ability to become magnetized by an external magnetic field.
The parallel multiple striations are the gradiometer's response to plow furrows in the soils which have a locally high level of magnetic susceptibility.
In many areas much early building utilized soft sedimentary rocks, which tend to be of relatively low magnetic susceptibility.
The parallel multiple striations are the gradiometer 's response to plow furrows in the soils which have a locally high level of magnetic susceptibility.Advertisement
