Indlela Yokubala Amandla Okudonsa Nokukhetha I-Neodymium Magnet Efanele Nge-Hook

Ungabala kanjani amandla okudonsa?

Ngokwemfundiso: Amandla okumuncai-neodymium magnet ene-hook ihlukaniswe cishe (amandla kazibuthe womphezulu ayisikwele × indawo yesigxobo) nge-(2 × vacuum permeability). Uma amandla kazibuthe womphezulu enamandla futhi indawo inkulu, kulapho ukumunca kunamandla khona.

Empeleni: Kufanele uyiwise phansi kancane. Kungakhathaliseki ukuthi into edonswayo iyisicucu sensimbi, ukuthi ubuso bayo bubushelelezi kangakanani, ibanga eliphakathi kwayo, nokuthi izinga lokushisa liphakeme kangakanani—konke lokhu kungenza buthaka amandla okudonsa. Uma udinga inombolo enembile, ukuyihlola ngokwakho kuthembeke kakhulu.

Yini okufanele uyibheke lapho ukhetha?

Isimo: Uma uyisebenzisa efemini, khetha leyo engakwazi ukumelana nobunzima; uma ulenga amathawula ekhaya, khetha amancane naphephile; uma ulenga ezindaweni ezinokushisa okuphezulu noma ezinomswakama, khetha leyo engakwazi ukugqwala futhi eqinile.

Umthamo womthwalo: Imithwalo elula (≤5kg) ingasebenzisa noma yimuphi omncane; imithwalo ephakathi (5-10kg) kufanele ibe yi-neodymium-iron-boron; imithwalo esindayo (>10kg) idinga eyezinga lezimboni—khumbula ukushiya umkhawulo wokuphepha ongu-20%-30%.

Amapharamitha: Hlola umthwalo omkhulu omakiwe. Omakethi abakhulu ngokuvamile banamandla kakhulu. Beka phambili imikhiqizo ethembekile.

Isifinyezo

Ungagxili kumafomula lapho ubala amandla okudonsa—izimo zangempela zinomthelela omkhulu. Uma ukhetha, qala ucabangele ukuthi izosetshenziswa kuphi nokuthi umthwalo usinda kangakanani, bese uhlola amapharamitha nekhwalithi. Lokho empeleni akunangqondo.
