N2 - The I-V curves of Bi-Sr-Ca-Cu-O superconductors were measured in DC magnetic fields, oriented both parallel and perpendicular to the tape surface, up to 33 T, 4.2 K, in resistive magnets at the National High Magnetic Field Laboratory. This paper presents the experimental set-up, results of critical current measurements, and an analysis of the obtained Ic(B) curves in terms of strongly and weakly linked current paths. A distinct double-step behavior is observed for field perpendicular to the tape surface. The scaling behavior of the applied field with its component perpendicular to the ab-plane, and the implied average grain-misalignment angle, is investigated.
