The high-*T*c superconducting (HTS) dynamo has recently been proposed as a new benchmark problem for the HTS modelling community. The benchmark geometry consists of a permanent magnet rotating past a stationary HTS wire in the open-circuit configuration and assumes for simplicity the 2D (infinitely long) case. [See benchmark #6](https://htsmodelling.com/benchmark-6).

In [Ainslie et al](https://iopscience.iop.org/article/10.1088/1361-6668/abae04), this benchmark problem has been implemented using several different methods, including **H**-formulation-based methods, coupled **H**–**A** and **T**–**A** formulations, the Minimum Electromagnetic Entropy Production method, and integral equation and volume integral equation-based equivalent circuit methods. Each of these approaches show excellent qualitative and quantitative agreement for the open-circuit equivalent instantaneous voltage and the cumulative time-averaged equivalent voltage, as well as the current density and electric field distributions within the HTS wire at key positions during the magnet transit.
