需要把这一段话翻译成英语



磁铁有一个“居里点”：
　　居里点，也称居里温度或磁性转变点。是指磁性材料中自发磁化强度降到零时的温度，是铁磁性或亚铁磁性物质转变成顺磁性物质的临界点。
　　19世纪末，著名物理家居里在自己的实验室里发现磁石的一个物理特性，就是当磁石加热到一定温度时，原来的磁性就会消失。后来，人们把这个温度叫“居里点”。不同材料的居里点是不一样的，铁：1040K；钴：1390K；镍：630K。
　　将磁铁放放在开水中，约373K，不到常见磁性材料的居里点，对磁性不会有什么影响。

Magnet has a “Courier point”:

Courier point is also called Courier temperature or magnetism transformation point. It means the temperature at which the self-magnetic strength of magnetic material drops to zero degree and such point is the critical point at which iron magnetism or ferrous magnetic materials transform to paramagnetic materials.

By the end of 19th century, famous physicist Courier found in his own laboratory a physical property of magnet. When the magnet was heated to certain temperature, its original magnetism disappeared. Later, people called this temperature “Courier point”. Different materials have different Courier points, iron: 1040K; cobalt, 1390K; nickel, 630K.

If magnet is put in boiling water, at about 373K, since it does not reach the Courier point of magnetic material, there is no impact on magnetism.
