Abstract
Critical current - magnetic field ($I_c$-B) relation is one of the basic properties of an HTS wire, which is needed for the design of performances of superconducting devices. Experimental results of the $I_c$-B relation of Bi-2223 and YBCO superconducting wire are presented in this paper. n-value is also an important parameter which is needed to calculate the electric field by using the power-law. Measurement results of the n-value of the same HTS superconducting wires are also presented.
