Tiivistelmä
This paper proposes two novel methods for upscaling the macroscopic magnetic field strength from the local solutions of B-conforming magnetoquasistatic multiscale problems. Unlike the volume average method classically used, these methods yield accurate values of the macroscale magnetic field for problems with strong locally-confined eddy currents which enables B-conforming multiscale formulations of eddy currents problems at higher frequencies.
