(a) Measurement results after precise local magnetic field compensation. Sub-figure shows condition with compensation; (b) Schematic diagrams of the measurement results before precise local magnetic field compensation. Sub-figure shows condition without compensation; (c) Magnetization curve; (d) Permeability curve; (e) Loss curve.
