Investigation of magnetic hysteresis in HTS coil by means of numerical modeling using T–A formulation

Year: 2025

Type: article

Abstract: Frequent task in the numerical modeling of superconducting magnets generating AC or pulsing fields is the evaluation of AC loss. Commonly, after solving the electromagnetic problem, the loss is calculated by integrating in time and volume the density of dissipated power, obtained locally as the product of electrical field and current density. However, the loss can also be determined from the product of current and voltage detected at the device terminations, in a way analogous to electrical measurements. Fortunately, this voltage signal can be easily determined in the frequently used T–A formulation. It can be further used for more detailed comparison with experimentin particular, the creation of magnetic hysteresis loops relating the flux linkage to the coil current. Methodology is illustrated on benchmark #3 problem published by the HTS modeling workgroup.
