Vm. Korablev et Lm. Tkachenko, CALCULATION OF MAGNETIC-FIELDS USING SURFACE CURRENTS AND LAW OF FULLCURRENT CONSERVATION, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 378(3), 1996, pp. 620-623
A method of magnetic fields calculation using the boundary integral eq
uations has been realized. The total field of magnetic induction B in
an arbitrary point is presented as the sum of two components. The curr
ent field B-c is defined by Biot-Savart law. The contribution B-s due
to the iron surface currents is calculated by the boundary integral eq
uations method involving the law of full current conservation to take
into account the volume magnetic flux distribution.
