This paper proposes two novel methods for upscaling the macroscopic magnetic field from the local solutions in magneto dynamic 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 current problems at higher frequencies.
