Currents having the form of a step function or a pulse flowing in a circular loop placed above a conducting medium occupying the half-space give rise to eddy currents within the conducting material. The loop is located either perpendicular or parallel to the dividing the two half-spaces surface. For the transient state the distribution of eddy currents is determined inside the conducting medium, the distribution of the magnetic field is also determined in the air region which occupies the other half-space.
Übersicht
Eine kreisförmige Leiterschleife, die über einem leitenden Halbraum senkrecht oder parallel zur Trennebene der beiden Medien angeordnet ist, wird von Strömen in Form einer Treppenfunktion oder eines Impulses durchflossen. Für den transienten Fall werden die Wirbelströme im leitenden Halbraum sowie das magnetische Feld im Luftraum berechnet.
