copper and chromium and having a maximum relative impedance permeability measured at 50 Hz of at least 200 x 10**3 G/Oe (0.25Tm/A), characterized in that the said parts have different curves of relative impedance permeability as a function of the temperature of measurement around the ambient...
INTRODUCTION WHEN we use the term magnetic permeability we ordinarily think of it as defined by the ratio of B/H = (μ), where B is expressed in gausses and H in gilberts per centimeter. It is the ratio of the flux in a magnetic circuit produced by a given magnetizing force to the...
quantified cTnI at an LOD of 0.5 ng/mL within four min using the resonant circuit [181]. In Kielys’ later work, the sensitivity limits of MPs to the RCM were investigated [182]. Barnett et al. integrated the RCM device (Fig. 4B) with a phase locked loop circuit and five coils...
At the beginning of this section we saw that the flux produced in a magnetic circuit, is proportional to the m.m.f and inversely proportional to the reluctance of the magnetic circuit. On this page, permeability has been described as a measure of how easy it is to set up a magnetic fie...
The experimental data have been compared with predictions of magnetic circuit model described for dynamic conditions. The applied model analyses the effect of the demagnetising field due to shape and size of ferrite particles.关键词: Theoretical or Mathematical, Experimental/ blending demagnetisation ...
Electrical inductance in serial and parallel connected inductors. Inductance The Electro Magnetic Field - EMF - induced into a electric circuit. Inductors - Stored Energy Energy stored in a magnetic field. Relative Permittivity - the Dielectric Constant Common materials and their relative permittivity...
J. Polydoroff refers to the advantages, particularly in the matter of selectivity, which result from tuning radio receiver circuits in such a manner that the ratio of tho inductance to the resistance of the circuit remains constant. These desirable results may be conveniently accomplished by a ...
Then, the difference of the measured oscillation frequencies is calculated and then the calculated difference is converted into a magnetic permeability or a dielectric permittivity. One sensor selectively detects a change in the magnetic permeability or a change in the dielectric permittivity of a ...

In experiments two different types of permeabilities are found. The relationship of the complex μ to the μdetermined from resistive losses in a circuit element and to the μdetermined from reactance changes is developed. A criticism is given of theories of ferromagnetic resonance. The status of ...
