The magnetic field of an arbitrary shaped defect in a plane-parallel plate

The problem of an arbitrarily shaped defect in a ferromagnetic half-space and a plane-parallel plate plate is solved. The solution is expressed as an integral equation in which the integration was performed only over the defect surface. This integral equation is solved by the iteration method, which...

Beschreibung
Zusammenfassung:The problem of an arbitrarily shaped defect in a ferromagnetic half-space and a plane-parallel plate plate is solved. The solution is expressed as an integral equation in which the integration was performed only over the defect surface. This integral equation is solved by the iteration method, which allows one to represent the solution as a series in powers of the small parameter . The numerical results are obtained for a defect in the form of an ellipsoid.
