The Biggest Magnet 最大的磁体 A: Whats the biggest magnet ever? 究竟什么是最大的磁体? B: Well, thats a great question. Well, for starters youd have to mention whoppers like the hybrid magnet at the National High Magnetic Field Lab in Tallahassee, Florida.This magnet weighs thirty-four tons and stands twenty-two feet tall.Giant magnets in hospitals, physics labs, and other facilities help in cutting edge research. However, even a magnet the size of a building cant compete with a magnet the size of a planet. 嗯，问得好。对于初学者来说，不得不提一下那些庞然大物，比如佛罗里达塔拉哈西的国家高磁场实验室的混合磁体。这块磁铁重34吨，立起来有22英尺高。医院，物理实验室和其他设备里的巨型磁体对尖端研究有帮助。然而，即使是一块建筑物大小的磁体也不能和一块行星大小的磁体相匹敌。 A: A magnet the size of a planet? 一块行星大小的磁体? B: The Earth itself is a magnet! Researchers think its the effect of convection currents in our planets molten interior that causes the entire Earth to behave as one gigantic magnet, with a North and South Pole.Whenever you look at a compass, what youre doing is reading the magnetic field of the planet on which you are standing. |
