想不想用磁铁做出各种有趣的东西?想不想利用磁铁移动其他物品?快来做实验吧!155曲别针锁链1.把金属曲别针拿到磁铁附近。曲别针有没有被吸过去的感觉?2.按照图中的样子,你能把多少个曲别针连成一串?磁铁靠近铁或镍这类金属的时候,会把它们吸过来。绝大部分曲别针都含有铁或镍,所以它们会被磁铁吸住。磁铁能吸住好几个曲别针,连成一串。当最下面的曲别针离磁铁太远的时候,磁铁磁力就会变弱,曲别针也就无法再被吸住了。
Do not want to use the magnet to make a variety of interesting things? Do you want to use the magnet to move other items? Come to experiment it! 155 clip chain 1. Take the metal clip near the magnet. Is there any feeling that the paperclip has to be sucked? 2. How many clips you can put together in a row as you can see in the picture? When the magnet is near a metal such as iron or nickel, it sucks in. Most of the paperclips contain iron or nickel, so they will be attracted by the magnet. Magnet can hold several paperclips, even into a string. When the lowermost clip is too far away from the magnet, the magnetic force of the magnet weakens and the clip can no longer be sucked.
