Abstract
The purpose of this thesis is to analyze, simulate, and experimentally verify the behavior of superconductors, materials of significant scientific interest and in ongoing research and development. Concerning the study of superconductivity, both finite element simulation and analytical analysis requires experimental calibration of the material properties This thesis’s work is focused in experimentally calibrating and optimizing these characterization methods. For this purpose simulations were conducted to analyze the electromagnetic behavior of two types of conductive tapes: copper and superconducting. These tapes were examined under two distinct thermal conditions—ambient temperature and immersion in liquid nitrogen. The simulations were carried out under both direct current (DC) and alternating current (AC) regimes.
They were developed and verified, in order to draw important considerations for the work carried out
