Determination of critical current density from arbitrary flux relaxation process
AIP Advances, 2012 The current-carrying ability of a type-II superconductor is generally represented by its critical current density. This can be determined by measuring a flux relaxation process starting with a testing current density that is greater than or equal to the ...

Radon release rate from soil into the surface atmosphere specifics
Vestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2021 The paper presents the results of the analysis of long-term series of monitoring data on the radon flux density. They were produced using a accumulation chamber of our own design, which allows, in terms of the readings of alpha radiation counters, to ...

Comparison of Two Finite-Permeability Subdomain Models for Surface-Mounted Permanent-Magnet Machines
IEEE Access, 2023 Subdomain models have been widely used to quickly model the fields and the torque of surface-mounted permanent-magnet machines (SMPMMs). Nevertheless, when magnetic saturation occurs, those models which assume the permeability of the iron parts to be ...

Approximation of Hysteresis Changes in Electrical Steel Sheets
Energies, 2021 This paper describes a simple method of approximating hysteresis changes in electrical steel sheets. This method is based on assumptions that flux density or field strength changes are a sum or a difference of functions that describe one curve of the ...
