The pulsed magnet described in this p aper operates at liquid nitrogen tem perature and is used for the direct me asurement of magnetocaloric effect of magnetic materials.It uses a relatively small pulsed power supply(22kW).With pulsed duration of 1?2?3?4and 5seconds,respectively.The solenoid has a bore diameter of 20mm.The magn et system has operated steadily to 2.232T at 180A in ex-periments.The uniformity of magnetic field is better than 1%within 10mm of solenoid center.It is satisfied f or the testing of magnetocaloric effect of magnetic materials.
