摘要：

A Bi-2212 oxide superconducting magnet has been cooled down to temperatures around 20 K employing a Gifford-McMahon (G-M) cryocooler. An a.c. magnetic field with a peak value of 0.44 T is stably generated at frequencies up to 0.25 Hz (0 T-->0.44 T-->0 T, 4 s per cycle) at almost-equal-to 20 K. The a.c. loss characteristics arising in the magnet are presented. The expected potential of the magnet for a.c. operation with a higher peak magnetic field is also discussed in terms of a.c. loss behaviour.
