LOSSES DUE TO FRINGING FLUX: ESTIMATION, TESTING AND AVOIDANCE

LOSSES DUE TO FRINGING FLUX: ESTIMATION, TESTING AND AVOIDANCE

​The fringing flux is an effect appearing in gapped magnetic, where the magnetic flux lines bulge outward due to mutual repulsion. This is translated into a modification of the inductance and a possible overheating in the wires surrounding the gap.
