The rotating pattern of permanent magnets (on the front face; on the left, up, right, down) can be continued indefinitely and have the same effect. The effect of this arrangement is roughly similar to many horseshoe magnets placed adjacent to each other, with similar poles touching. The effect was discovered by John C. Mallinson in 1973, and these "one-sided flux" structures were initially described by him as a "curiosity", although he recognised at the time the potential for significant improvements in magnetic tape technology.〔J.C. Mallinson, ("One-Sided Fluxes — A Magnetic Curiosity?" ), ''IEEE Transactions on Magnetics'', 9, 678-682, 1973, 〕 In the 1980s, Lawrence Berkeley National Laboratory physicist Klaus Halbach independently invented the Halbach array to focus particle accelerator beams.〔("Magnetically levitated train takes flight" )〕 ==Flat Halbach arrays== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Halbach array」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
