| 摘 要： | 采用经典电磁场、有限元数值计算两种方法，设计了一种用于磁热效应直接测量的脉冲螺线管磁体，在螺线管磁体中心处，磁感应强度的计算值及测量值均在2．2T(180A电流时)，且它们之间的误差很小；在以螺线管中心为球心，直径为10mm球内，磁感应强度的均匀度优于1％，达到了脉冲磁体的设计要求。

Theoritic Design of Pulsed Magnet for Direct Measurement of Mganetocaloric Effect |
| |
| Abstract: | A pulsed solenoid magnet, which is applied for direct measurement of magnetocaloric, is designed by classical electromagnetic method and finite element numerical value calculation method. In the center of solenoid, the magnetic induction strength is about 2.2T when the current is up to 180A. In 10mm spherical space near the center of solenoid, the nonuniformity of magnetic induction strength is less than 1%. The pulsed magnet accords with the demand of design. |
