摘要
简述了磁热效应的原理及磁致冷技术的发展现状.使用纳米磁流体为工作物质设计了室温磁热效应演示实验,通过灵敏电流计光标的偏转角度显示温度的变化.
The principle of magnetothermal effect and the progress of magnetic refrigeration are introduced briefly. A demonstration experiment of magnetothermal effect in normal room temperature is designed using nanometer hydromagnet as working matter. The temperature change is displayed by the deflection degree of cursor of galvanometer.
