Magnetic-flux and eddy-current distributions at epstein corner lap joints

The magnetic-flux and eddy-current distributions in the neighbourhood of double-lap corner junctions between magnetic strips are investigated numerically. The results cover a wide range of material anisotropy and relative gap reluctance, but are restricted to linear dependence of B on H. Reverse flux transfer is predicted in some regions of overlap when the gap reluctance is low and the easy direction of magnetisation is perpendicular to the strip length. Corner corrections are provided for both permeability and loss measurements.
