Abstract: Superconductor magnets hold immense promises for strong magnets based on the fascinating nature that high current can flow with negligible Joule-heating loss dissipation. They have indeed enabled disruptive technology in high-field applications. In the past years, low-temperature superconductor (LTS) magnets have played a key role in high-field research. However, the practical limit of the maximum field intensity of LTS magnets has been reached. Hence, no-insulation (NI) high-temperature superconductor (HTS) magnet technology has been spotlighted, and relevant research has been widely performed. As a result, through numerous high-field NI HTS magnet research endeavors, it is confirmed that key challenges in developing high-field NI HTS magnets are detrimental effects caused by screening current and NI behavior. To resolve this issue, we have developed multiple numerical simulation methods that allow researchers to investigate screening current-induced effects. With further experimental studies, we have verified that our numerical simulations are applicable to the investigation of screening current-induced effects generated by HTS magnets. In this talk, we present multiple numerical simulation methods based on the finite element method. In addition, we also present a numerical simulation method with the partial element equivalent circuit to investigate NI behaviors.
