Penetration loss in BSCCO tape without transport current

A penetration loss formula for superconducting tapes has been derived in ou r previous work. In this paper, the orientation of the magnetic field is co nsidered represented with power law and the magnetic field dependence of th e critical current density. The analytical estimations with the formula are compared with experimental results on the magnetization loss for BSCCO tap e with no transport current for several field orientations. The losses esti mated by this formula agrees well with the experimental results, when the m agnetic field is applied parallel or perpendicular to the tape face. For th e magnetic field with another field orientation, the experimental results a re smaller than the analytical predictions, because of the demagnetizing ef fect.
