Nkọwa dị mkpirikpi:
Ụkpụrụ nke Halbach array bụ iji nhazi pụrụ iche nke nkeji magnet iji kwalite ike ubi na ntụziaka otu.
Kpọmkwem, na n'usoro Halbach, a na-ahazi ntụgharị magnetization nke magnet dị ka otu iwu siri dị, nke mere na oghere magnetik dị n'otu akụkụ na-emewanyewanye nke ọma, ebe magnetik dị n'akụkụ nke ọzọ na-ada mbà ma ọ bụ ọbụna dị nso na efu. Nhazi a nwere ike imeziwanye arụmọrụ nke oghere ndọta, yana a na-ejikwa ya n'ọhịa nke moto na magnetik levitation.
A na-agbanwegharị vector magnetization nke ezigbo linear Halbach array dị ka eriri sinusoidal si dị, ya mere a na-ekesa otu akụkụ nke oghere magnetik ya dị ka iwu sine siri dị, akụkụ nke ọzọ bụ oghere magnetik efu. Linear Halbach arrays bụ nke a na-ejikarị na moto linear, dị ka ụgbọ oloko maglev, otu n'ime ụkpụrụ ndị a bụ ike nkwusioru sitere na mmekọrịta nke magnet na-akpụ akpụ na oghere magnetik na-emepụta site na induction ugbu a na onye nduzi, magnet a na-enwekarị obere ibu. , ike ndọta, elu ntụkwasị obi chọrọ.
Enwere ike ile usoro Halbach cylindrical dị ka okirikiri okirikiri kpụrụ site na ijikọ ogologo Halbach array end na ngwụcha. Otu dị ka linear Halbach array bụ na magnetization direction nke magnet na-adịgide adịgide siri ike ịgbanwe na-aga n'ihu na gburugburu, ya mere na n'ezie ọrụ, cylinder na-ekewa n'ime M ngalaba magnets nke otu size.
1.Directional ndọta nkwalite: AnyịHalbach arrays nwere ike iwepụta oghere ndọta siri ike n'ụzọ dị iche iche, na-abawanye ike nke oghere ndọta nke ukwuu ma e jiri ya tụnyere usoro ndọta nkịtị.
2.Efficient ndọta itinye n'ọrụ: Site na nhazi magnet nke ejiri nlezianya mee ya, usoro Halbach na-enwe ike itinye uche magnetik n'otu ebe, na-ebelata ihe mkpofu na nkwụsị nke oghere magnet.
3.Precise ndọta njikwa： Site n'ịgbanwe nhazi na akụkụ nke ndọta, usoro Halbach nwere ike nweta mgbanwe mgbanwe nke ntụzịaka oghere ndọta iji nweta njikwa mpaghara ndọta ziri ezi, yana anyị nwere ike ijikwa ndọta ndọta.n'ime 3°.
4.Igwe ntuzi aka magnetik: Usoro nrụpụta dị elu na akụrụngwa na-eme ka nrụpụta nke ọma na ịdị mma nke usoro Halbach. Usoro nhazi magnet na nhazi ziri ezi na-eme ka ịdị n'otu na nkwụsi ike nke oghere magnetik, na-ebelata mgbanwe na njehie nke oghere magnet.
5.High mma magnets :ụlọ ọrụ anyị nwere ike ịnye ngwaahịa ike magnetik dị elu, nkwụsi ike dị elu nke samarium cobalt maka mmepụta nke Halbach array.
1.Electric igwe ubi
2.Sensọ ubi
3.Magnetic levitations
4.Medical ubi: dị ka magnetik resonance imaging (MRI), magnetik ọgwụ akụrụngwa
5.Na mgbakwunye na ubi ndị dị n'elu, Halbacharray nwekwara ngwa dị iche iche na mbara igwe, nzikọrịta ozi eletrọnịkị, njikwa akpaaka na mpaghara ndị ọzọ.
