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...

12.4.1.5Eddy current The principle of theeddy current testingis based on the interaction betweenmagnetic fieldand material. This interaction generates eddy currents in the specimen and captured by the system; seeFig. 12.13[80]. Therefore, it is possible to detect defects such as small cracks by...
The magnetic alignment of electroconductive particles with shape anisotropy under a rotating magnetic field is reported. It is theoretically demonstrated that a coil aligns parallel to the plane of the rotating magnetic field. The phase delay of a resistor-inductor (RL) circuit represented by a coil...
The eddy current solver computes steady-state, time-varying (AC) magnetic fields at a given frequency – this is a frequency domain solution.All objects are stationary. The source of the static magnetic field can be: Sinusoidal AC current (peak) in conductors.Time-varying external magnetic ...
