  Flux jumps lead to 10-20 times reduction of the shielding currents at a
pulsed field magnetization of a melt-grown HTS annuli. The induced circular
currents and the related trapped field are small after a field pulse since the
duration of the pulse is shorter than the temperature relaxation time (<<1 s).
Moreover, the residual trapped field in the hole of the annuli has the opposite
direction in respect to the applied field. It is shown that the small value of
the induced circular currents at the relatively high average critical current
density is related to a narrow angular region of the flux motion (approximately
7 deg).
