This paper presents the local magnetic properties measured in a three-phase induction motor model core. The relationship between the magnetic field strength vector H and the magnetic flux density vector B was obtained by measurements with a special sensor using the H-coil method and the double-needle method. As a result, the relationship between the H-vector and the B-vector was clarified, and it is shown that the local properties in an actual core are vectorial in nature.
