低温的世界不仅是白皑皑的冰雪天地,还有着许多让我们惊叹并且受益无穷的地方。神秘的磁性常温下含有铁钴镍等金属的材料可以获得磁性,然而非金属材料在低温下也能表现出磁性,这种磁体适用于制造新型计算机存储设备,绝缘设备等。但这类材料在温度超过一定限度时就会失去磁性。临界温度最高的非金属磁体在-230℃左右,即使施加高压也仅能提高到-208℃。空气魔术师 Low-temperature world is not only white and snowy world, there are many amazing and we benefit from the endless. Magnetism Magnetic materials containing iron, cobalt, nickel and other metals at room temperature are magnetically available, however, non-metallic materials can also exhibit magnetism at low temperatures. Such magnets are suitable for the manufacture of new computer storage devices, insulating devices, and the like. However, such materials lose their magnetism when the temperature exceeds a certain limit. The highest critical temperature of non-metallic magnets at -230 ℃, even if the high pressure can only be increased to -208 ℃. Air Magic
