Bi-based oxide superconductors show high critical current density even in very high magnetic fields. This means that they could be used to high field superconducting magnets. In this paper, the flux-jump stability of HTSC superconducting magnets was studied. A critical state model is proposed for HTSC which shows anisotropy and weak-link, the effects of anisotropy and weak-link on the stability are discussed. The mechanical stability was also considered
