Abstract :
AC losses in bulk high-temperature superconductivity rods are calculated using the finite element method. The effect of anisotropy is introduced to the E-J power law considering field dependent critical current density along the axial and azimuthal direction. Influence of the external field on the ac loss components is investigated
