Abstract A simple method for evaluation of the lower limit of intragrain magnetic flux motion viscosity is presented. We have also shown that in our experiment the energy loss in an alternating magnetic field in a granular YBa2Cu3O7−x superconductor prepared by the standard sintering method is determined by thermally assisted magnetic flux flow into superconducting grains and does not depend on the intergrain space.
