Further Information

The inductive method for measuring the critical current density is investigated by means of the numerical simulation. In the method, the ac magnetic field is generated by using a small coil placed just above the high-temperature superconductor and the third-harmonic voltage induced in the coil is detected. In order to calculate the harmonic voltages, the numerical code has been developed for analyzing the time evolution of the shielding current density. As the J-E constitutive relation, the power law is assumed. By means of the code, the third-harmonic voltage is evaluated as a function of the coil current. The results of computations show that, above a certain limit of the coil current, the third-harmonic voltage grows more rapidly than any other one. In addition, it is found that the square root of the third-harmonic voltage is roughly a linear function of the coil current.
