| Popis: | Trapped fields and stresses are examined through one- and two-dimensional (axisymmetric three-dimensional) solutions when a bulk high-T/sub c/ superconductor (HTS) is fully magnetized by field cooling. The shape factor of the bulk magnet is discussed analytically with ring currents, since the maximum trapped field depends strongly on its shape. The stresses in the bulk HTS are numerically evaluated with the finite-difference method in the framework of the Bean model. Differences between one- and two-dimensional solutions are examined in terms of the maximum tension stress and shear stress. |
