In this work, we exposed a high-temperature superconducting (HTS) tape to a rotating magnetic field, and measured ac losses using a calorimetricmethod based on the temperature rise caused by the ac loss. To compare the characteristics of the other ac loss conditions, we measured the magnetization losses in the uniform ac magnetic field perpendicular and parallel to the HTS tape face. The losses in the rotating magnetic field are the same as in the perpendicular magnetic field. In addition, we measured the influence of the rotating magnetic field waviness on the ac loss characteristics.
