Uluhlu lweHalbach lwacetywa okokuqala nguKlaus Halbach ngo-1980 kwaye ukusukela ngoko yaba sisisombululo esidumileyo kumashishini ahlukeneyo, kubandakanya i-aerospace, ezonyango, kunye neenqwelomoya.
Enye yeenzuzo eziphambili zeemagnethi zoluhlu lweHalbach kukukwazi kwabo ukuvelisa umhlaba owomeleleyo wemagnethi kwelinye icala ngelixa usenza intsimi ephantsi kakhulu kwelinye. Le propati ibenza ukuba balungele ukusetyenziswa kwizicelo apho kufuneka umhlaba ogxininisiweyo wemagnethi, onje ngeebheringi zemagnethi, iimotor ezinear, kunye ne-particle accelerators.
Iimagnethi zoluhlu lweHalbach zinokulungiswa ukuze zihlangabezane neemfuno ezithile zezicelo ezahlukeneyo. Zinokuthi ziyilwe ngokweemilo kunye nobukhulu obahlukeneyo, kubandakanywa i-cylindrical, i-rectangular, kunye ne-ring-shaped configuration. Oku kuvumela abaqulunqi kunye neenjineli ukuba benze izisombululo zemagnethi ezilungelelaniswe neemfuno zabo ezithile.
Ukongeza, iimagnethi zoluhlu lweHalbach zibonelela ngoxinaniso oluphezulu lwemagnethi kunye nokusebenza kakuhle, okubenza babe sisisombululo esinexabiso eliphantsi kwizicelo ezifuna iimagnethi ezisebenza kakhulu. Bakwabonelela ngokugqwesileyo kozinzo lobushushu kwaye banokusebenza kwiindawo ezirhabaxa.
Lilonke, iimagnethi zeHalbach zisisisombululo esiguquguqukayo nesisebenzayo kuluhlu olubanzi lwezicelo ezifuna indawo egxilwe kunye neyomeleleyo yamagnetic. Ngokukwazi kwabo ukulungelelaniswa ukuhlangabezana neemfuno ezithile, banikezela ngesisombululo esisebenzayo kunye neendleko ezisebenzayo kubaqulunqi kunye neenjineli kumashishini ahlukeneyo.

Iingenelo
I-Halbach array lulungiselelo olukhethekileyo lweemagnethi ezisisigxina ezidala intsimi yemagnethi eyomeleleyo kwaye efanayo kwelinye icala, ngelixa ucima indawo yemagnethi kwelinye icala. Olu qwalaselo olulodwa lubonelela ngeenzuzo ezininzi ngaphezulu kweNs yemveli (emantla-emazantsi) ulandelelwano lwemagnethi.
Okokuqala, uluhlu lweHalbach lunokuvelisa indawo eyomeleleyo yamagnetic kunolandelelwano lwe-NS. Oku kungenxa yokuba iimagnethi zemagnethi nganye zilungelelaniswe ngendlela yokuphucula imagnethi epheleleyo kwelinye icala, ngelixa inciphisa kwelinye icala. Ngenxa yoko, uluhlu lweHalbach lunokuvelisa ukuxinana okuphezulu kwe-flux kunolungiselelo lwemagnethi lwendabuko.
Okwesibini, uluhlu lweHalbach lunokwenza indawo efanayo yamagnetic kwindawo enkulu. Kulandelelwano lwe-NS yemveli, amandla emagnethi ayahluka ngokuxhomekeke kumgama osuka kwimagnethi. Nangona kunjalo, uluhlu lweHalbach lunokuvelisa indawo efanayo yamagnetic kwindawo enkulu, eluncedo kwizicelo ezifuna umhlaba ohambelanayo kunye noqikelelo lwemagnethi.
Okwesithathu, uluhlu lweHalbach lunokusetyenziselwa ukunciphisa ukuphazamiseka kwamagnetic kunye nezixhobo ezikufutshane. Ukucinywa kwemagnethi kwelinye icala loluhlu kunokunciphisa uphazamiseko lwemagnethi nezinye izixhobo ezikufutshane okanye izixhobo. Oku kwenza uluhlu lwe-Halbach lulungele izicelo ezifuna ukuchaneka okuphezulu kunye nokuphazamiseka kwemagneti ephantsi.
Lilonke, izibonelelo zoluhlu lweHalbach ngaphezulu kolandelelwano lwe-NS lubandakanya umhlaba owomeleleyo wemagnethi, indawo efanayo yamagnetic ngaphezulu kwendawo enkulu, kunye nokunciphisa ukuphazamiseka kwemagneti kunye nezixhobo ezikufutshane. Ezi zibonelelo zenza uluhlu lweHalbach lube lukhetho oludumileyo kwiinkqubo ezahlukeneyo zokusebenzisa, kubandakanya iimotor, iijenereyitha, izinzwa, kunye neenkqubo zokutsalwa kwemagnethi.
