铁磁性材料居里点的简易测定

本实验描述了一种测量铁磁性材料居里点的方法,其原理是观察磁滞回线的消失。与其它方法相比,具有直观、形象、测量准确的优点,而且装置简单易于操作。对铁和镍的测景结果表明,测最误差与文献值相比在摄氏两度以内。

AN EASIER METHOD OF MEASURING CURRE POINTS OF FERROMAGNETIC MATERIALS

An easier method of measuring Curre Points of ferromagnetic materials has been presented through an experiment. Its principle is to observe the disappearance of the magnetic hysteresis loop. This method has the advantages of vividness, intuition, and accuracy over other methods, and the appartus used is simple and easy to operate. The results obtained from measuring the value of iron and nickel show that the error is within 2 centigrade compared with that in the literature.
