Magnetization and flux capture in a superconducting ring made of high-T${}_{c }$2G tape

This article presents a theoretical examination of magnetization processes and magnetic flux capturing in a superconducting ring. Additionally, experimental investigations of magnetic flux trapping in a ring made of second-generation high-temperature superconducting tape were performed. The obtained experimental results are in excellent agreement with the theoretical model. Furthermore, the critical current in zero magnetic field was measured using a well-established non-contact method based on the capture of magnetic flux within the ring, and these data align with manufacturer-provided values. The method for determining the critical current was further modified by applying a local magnetic field to a small region of the ring. This modification allowed for the study of the critical current dependence on the magnitude and orientation of the magnetic field, providing a straightforward and reliable means of determining the critical current and its anisotropy.
