TL;DR: In this paper, a 3D magnetic properties tester for laminated silicon steel specimen has been designed and constructed, where the magnetization structure is the critical part of the tester especially for the magnetic properties of the laminate silicon steel in the perpendicular direction of grain oriented.

TL;DR: In this paper, the authors investigated the frequency-dependent transport ac losses of two representative commercial coated superconductors (CCs) at tens of kilohertz band and established a circuit model to understand the underlying mechanism, and found that the current in metal components is not commonly thought eddy current, but a transport current driven by the power supply and surrounding magnetic fields.

TL;DR: A generalized finite element method (GFEM) is proposed to calculate the forward problem accurately and is capable of achieving better accuracy using less computational time and memory with GFEM.

TL;DR: In this article, the authors proposed a new algorithm that updates model parameters with magnetization history to modify the Tellinen model, which can consider the return-point memory effect to describe the static hysteresis loops containing minor loops.

TL;DR: In this paper, the authors developed a new detection system for the first time to detect the gas concentrations of the SF6/N2 mixture in extra/ultra-high voltage power transmission systems.
