叠加苦碟子放进一块磁铁线圈。
我们构建的电阻磁铁在国家高磁场实验室的highest-field电阻磁铁。爱游戏体育是什么爱游戏提现客服他们使用的技术我们称之为佛罗里达苦磁铁技术发明在塔拉哈西。方法是首先由弗朗西斯苦在1930年代,因此得名“苦磁铁”。The magnets that he made were fairly simple. Here, in the 1990s, we improved the technology dramatically, increased the efficiency of the magnets by 40 percent by optimizing the shape and spacing of the cooling holes. Hence we call the magnets we build here Florida Bitter magnets. They use copper sheet metal with lots of cooling holes in it. We have insulating sheets with the same cooling hole pattern. We stack them into a helix, then put voltage across the coil. High currents flow through the coil, typically about 40,000 amps. Cold water flows through the cooling holes at a speed of about 45 MPH. If you didn't have the cooling water, the magnet would melt in a couple hundredths of a second. Four of the five largest magnet labs in the world now use the Florida Bitter magnet technology.
