Halbach cov hlau nplaum sib xyaw yog kev npaj tshwj xeeb ntawm cov hlau nplaum ruaj khov uas ua rau thaj chaw sib nqus ntawm ib sab ntawm cov kab muaj zog dua, thaum tshem tawm thaj tsam ze ze xoom ntawm lwm sab. Qhov no txawv ntawm qhov sib nqus ntawm ib puag ncig ib leeg. Nrog ib tus hlau nplaum, koj muaj lub zog sib nqus sib nqus ntawm ob sab ntawm cov hlau nplaum.

Qhov tshwm sim tau pom thawj zaug los ntawm John C. Mallinson hauv xyoo 1973, thiab cov "ib leeg ib sab ntws" cov qauv tau piav los ntawm nws ua qhov xav paub. Xyoo 1980s, kws kho mob lub cev Klaus Halbach tau tsim nws tus kheej los ntawm Halbach array kom tsom mus rau kab teeb ci, hluav taws xob thiab lasers.

Ib qho ntawm Halbach hlau nplaum arrays yog linear thiab cylindrical. Cov qauv kab teeb tsa feem ntau yog siv hauv cov tshuab hluav taws xob, xws li tsheb ciav hlau maglev; Cylindrical array qauv yog siv feem ntau hauv cov tshuab hlau nplaum tas mus li, xws li cov ntshav ntws tawm lub cev muaj zog hauv lub plawv mob lub cev. Kev tsom mus rau thaj chaw sib nqus ntawm cov qauv cylindrical array kuj tseem haum rau cov hlab nthwv dej mus rau kev sib txuas xov tooj cua, radar microwave magnetron, thiab lwm yam.
