Modelling Interactions Between HTS Tapes and Permanent Magnet Fields in an HTS Dynamo

, 2021
The interactions between a permanent magnet (PM) and a coated conductor tape lies at the heart of several types of high-temperature superconducting (HTS) devices, including the HTS dynamo. The applied magnetic field from a PM is typically highly spatially inhomogeneous with large field gradients occurring near the edges of the PM.
