A magnetic field of 70 to 100 T or more is usually called an ultra-strong magnetic field. Since 100 T is 1 megagauss (1 MG = 10 6 G) in the CGS Gaussian system, ultra-strong magnetic fields are often also called megagauss magnetic fields. [How it occurs] Since CM Fowler and his colleagues at the Los Alamos National Laboratory in the United States announced the generation of an ultra-strong magnetic field exceeding 1000 T in 1960, research has been conducted into the generation of ultra-strong magnetic fields using various methods. Ultra-strong magnetic fields are generated by passing a large current instantaneously through a circular circuit (coil) by some method. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
ふつう,70ないし100T以上の磁場を超強磁場という。100TはCGSガウス単位系では1メガガウス(1MG=106G)であるので,超強磁場はしばしばメガガウス磁場とも呼ばれる。 [発生方法] 1960年にアメリカのロス・アラモス研究所のC.M.ファウラーらが1000Tをこえる超強磁場の発生を発表して以来,いろいろな方法による超強磁場発生の研究が行われている。超強磁場は,なんらかの方法によって瞬間的に大電流を円形回路(コイル)に流すことによって発生される。 出典 株式会社平凡社世界大百科事典 第2版について 情報 |
