Sistemụ Igwe Ọdụdọ Halbach Array

Halbach array bụ ihe ndọta, nke bụ ihe owuwu kacha mma na injinia. Ebumnuche bụ imepụta oghere ndọta kachasi ike yana ọnụ ọgụgụ kacha nta nke magnet. N'afọ 1979, mgbe Klaus Halbach, bụ ọkà mmụta America, mere nnwale electron acceleration, ọ chọtara ihe ndọta a pụrụ iche na-adịgide adịgide, jiri nwayọọ nwayọọ mee ka usoro a dịkwuo mma, ma mesịa guzobe ihe a na-akpọ "Halbach".

Kedu ihe bụ Halbach Array Magnets

A Halbach Array bụ ihe ndọta ndọta nke na-emepụta oghere ndọta dị elu na-eji ndọta na-adịgide adịgide, ahaziri ya na vector oghere ndọta na-atụgharị nke nwere mmetụta nke ilekwasị anya na ịbawanye oghere ndọta n'otu akụkụ, ebe ịkagbu ya n'akụkụ nke ọzọ. Halbach Arrays nwere ike nweta njupụta njupụta dị elu na otu na-enweghị mkpa ntinye ike ma ọ bụ jụrụ oyi, nke electromagnet ga-achọ.

Akara Halbach bụ nhazi pụrụ iche nke ihe ndọta na-adịgide adịgide nke na-eme ka oghere ndọta dị n'otu akụkụ nke usoro ahụ sie ike, ebe ọ na-akagbu ogige ahụ na nso efu n'akụkụ nke ọzọ. Nke a dị nnọọ iche na oghere ndọta gburugburu otu ndọta. Site na otu ndọta, ị nwere ike ndọta nhata n'akụkụ abụọ nke magnet, dị ka egosiri n'okpuru:

N'ụzọ dị iche, usoro Halbach nke egosiri n'aka nri nwere ubi siri ike n'elu, yana ubi na-adịghị ike na ala. E gosipụtara otu ndọta ebe a dị ka cubes 5 dị ka usoro Halbach, mana na okporo osisi niile nke ugwu na-atụ aka elu. Magnetically, nke a bụ otu ihe ahụ dị ka otu ndọta ogologo.

John C. Mallinson chọpụtara na mbụ mmetụta a na 1973, ya na mbụ kọwakwara ihe owuwu ndị a "otu akụkụ" dị ka ọchịchọ ịmata ihe (njikọ akwụkwọ IEEE). N'afọ ndị 1980, ọkà mmụta physics Klaus Halbach chepụtara onwe ya n'usoro Halbach iji lekwasị anya n'ibe, electrons na lasers.

Halbach Arrays na teknụzụ ọgbara ọhụrụ

Ọtụtụ akụkụ nke teknụzụ ọgbara ọhụrụ bụ nke Halbach array kwadoro. Dịka ọmụmaatụ, Halbach cylinders bụ cylinders magnetized nke nwere ike ịmepụta oghere ndọta siri ike mana nwere ya.
