Eddy current magnetic field degaussing systemPROBLEM TO BE SOLVED: To enable sure detection of the changing value only of an eddy current magnetic field accompanied by the fluctuations of a hollow structure body which is not caused by the change in the geomagnetism.今岡 博生...
–This workshop introduces the Eddy Current solver based on a simple example with a disk above a coil. This solver calculates the magnetic fields at a specified sinusoidal frequency. Both linear and nonlinear (for saturation effects) magnetic materials can be used. Also, eddy, skin and proximity...
Eddy Current Definition: Eddy currents are loops of electric current induced within conductors by a changing magnetic field. Eddy Current Loss: In transformers, eddy currents cause energy loss as heat, which can be minimized by using laminated cores. ...

1. From what I understand, the current used in this mode is typically sinusoidal. Thus, when a sinusoidal current flows, the generated magnetic field changes over time, inducing an electric field in the opposite direction according to Maxwell's equations. Consequently, when a sinusoidal current ...
The eddy current lossesP in a conducting hollow circular cylinder slowly rotating in a homogeneous magnetic field perpendicular to its axis are calculated for an arbitrary lengthl and an arbitrary ratio λ of the inner and outer cylinder radii. The results allow an electrodeless resistivity determinat...
AC-DC, magnetic filed (MF). I create a square (air material), my object (aluminum) and the defect (air). I create two magnetic filed: first magnetic field for inferior and superior border Hx=cos(omega*t) Hy=0 Hz=0 second magnetic filed for right and left border : ...

Similar magnetic circuits are formed by the permanent magnets 13a. When the brake drum 7 rotates across the magnetic field extending radially outwardly from the permanent magnets 13a and 14a to the inner peripheral surface of the brake drum 7, an eddy-current is generated which produces a ...
As a result, an intense AC magnetic field can be efficiently obtained by a comparatively small driving AC current in comparatively low frequency range.doi:US4933657 AKazuo BesshoMasato EnokizonoUSUS4933657 * 1989年7月31日 1990年6月12日 Kanazawa University Eddy current type multilayered coil for ...
