Inducing magnetic field, having a first plate (A) of insulating material having a first face (A1) on which is formed a first track (5) of electrically conductive material, said first track (5) a spiral shape extending with respect to an axis (6), wherein the first plate (a) a ...
FIELD: electromechanical engineering; electromechanical and electrical devices requiring homogeneous magnetic field in air gap for normal operation.;SUBSTANCE: proposed inductor has separate pre-magnetized and cut cylindrical permanent magnets mounted in nonmagnetic shell; pre-magnetized cylinders are cut over ...
The computed result generally overpredicts the pressure measurement, and the data also exhibits an unusually large data scattering band due to the unstable glow discharge pattern in the presence of an applied and uniform magnetic field [31,41,46,47]. As anticipated, the magnetic field generates ...
More importantly, external permanent magnets, which are often too bulky to limit the device miniaturization and portability, are unnecessary as the inductor coil is both detector and magnetic field generator. In addition, coil inductance measurement is steady and time-saving and low power is consumed...

(~4 ohm) is probably due to the inductor’s AC resistance at 116kHz is much higher. The higher AC resistance is likely cause by the skin effect. Furthermore the capacitors also add parasitic AC resistance at high frequency. In summary, for high-current and strong AC magnetic field ...
Multiple \(f\)FMR peaks normally can originate from stripe magnetic domains due to perpendicular magnetisation43. The effect of magnetic domain structure on the permeability spectrum of the films can be negated, if any, to a single domain by saturating the films using a bias magnetic field. ...
At the typical frequency of 3 MHz the EM field penetrates into the thin skin layer of 1.3 mm in solid Si, 0.27 mm in molten Si, and 0.04 mm into the Ag inductor. The rest of the conducting bodies are free from the EM field. Using Maxwell's equations in quasi-static approximation, ...
