摘要：

Two types of contactless methods for measuring the critical current density have been investigated numerically. For the purpose of reproducing the experimental results numerically, the behavior of the shielding current density is formulated by use of the currentvector-potential method. A numerical code has been developed for solving an initial-boundary-value problem of the resulting integraldifferential equations and, by use of the code, both the inductive method and the permanent-magnet method are simulated successfully.
