Abstract In the study of magnetic field and magnetization distribution generated by Halbach permanent magnet array, the relationship functions M(H), M(B) and B(H) among magnetization (M), magnetic field strength (H) and magnetic induction (B) are involved. Here the experimental characteristics of these functions are introduced, and it is illustrated that M(B) function should be used in the calculation for obtaining the self consistent magnetization and field distributions inside the permanent magnet array. At the material interior of permanent magnet array, the sophisticated vectorial distributions of field and magnetization may not be experimentally measured, inappropriate use of M(H) and B(H) functions possibly results in the untrue predication of magnetic field and magnetization distributions under the intense self field.

Key words： Halbach permanent magnet array magnetic induction self-consistent distribution of magnetic field and magnetization
