The magnetization loss model in HTS tape when the magnetic field is exposed to the HTS tape face is suggested to be a Brandt model. In the case of a thin HTS tape, when the magnetic field exposed perpendicular to the HTS tape axis and the tape face is rotated, the magnetization losses correspond with Brandt model when the linkage magnetic field exposed. We previously reported the AC loss characteristic in a Bi2223/Ag tape applied a magnetic field in all direction. With decrease in the angle of the tape axis to the magnetic field, the magnetization losses are reduced. To complete the model of the magnetization loss in HTS tape, we suggest a new model for all magnetic field directions. It was reported that the critical current and cross-section are affected by the magnetization loss characteristics. We used three types of HTS tape, Bi2223/Ag tape measured previous report, new Bi2223/Ag tape in which the critical current is higher than in the previous experiment, and YBCO tape, to compare the magnetization loss model. Our new model is based on the measured magnetization losses because the loss is affected to the intrinsic critical current distribution and cross-section. The conditions of the base magnetization losses consist of the magnetic field exposed perpendicular to the tape axis and parallel to the tape face, perpendicular to the tape axis and perpendicular to the tape face, and parallel to the tape axis. The model enables us to induce the magnetization losses in response to charge in the amplitude of the magnetic field, the angle of the tape axis, and the angle of the tape face. This model corresponds with the magnetization losses in each tape in all magnetic field directions.
