Indlela yokwenza uzibuthe?

Sonke ejwayele ngale ndaba ayinzima, Ifana nozibuthe. Ekuphileni kwethu kwansuku zonke ngokuvamile isetshenziswa abantu ngenxa yekhono layo ukuheha izinto ezincane kusuka metal ezithile. Ngaphezu kwalokho, odonsa kabanzi emikhakheni eminingi, isibonelo, emsebenzini wokukhiqiza ugesi. Eqinisweni, kukagesi ngaphandle kwabo ngeke kwenzeke. Magnets kukhona eletromagnitov core - amadivayisi nokuphehla ugesi. Kodwa kusenzima akubona bonke. Emizimbeni yethu biotoki futhi zisenza sibe le imigqa yamandla kazibuthe omhlaba. Iplanethi yethu, singasho - kungcono uzibuthe omkhulu okwesibhakabhaka, njengoba edonsa amandla omkhulu Luhambo. Kunezindawo lapho nje udinga ukusebenzisa namandla amakhulu kazibuthe. Ngokwesibonelo, ephakamisela imikhumbi lushone, Fusion nokuningi.

Abantu ezikhathini zasendulo babeba wafunda ngokusebenzelana odonsa futhi izakhiwo zawo aqala sizisebenzise. Nokho, ngalezo zinsuku kwaba nje izingcezu magnetite, noma Lodestone, njengoba namuhla asebebizwa ngokuthi. Ezikhumbuzo kuqala ukuqomisana amadoda nabo kutholakele phakathi kumbiwa ngo emazweni iMelika Ephakathi. Lokhu ebaziwe ukuthi ezibaziweyo kusukela amabhlogo omkhulu zalolu hlobo, ngenxa isimo sabo, abacwaningi ngokuthi "amanoni umfana". Imigqa yamandla kazibuthe omhlaba ukuxhuma lezi zibalo uma bephuma esiswini. Ngaphezu kwalokho, uzibuthe wemvelo kanye izakhiwo zalo bachazwa emibhalweni yesandla yamaShayina yasendulo. Lokhu kwaziswa, itshe-nsimbi, yensimbi oxides luhlobene nezincazelo has impahla edonsa ezihlukahlukene yensimbi noma steel izihloko. Kwakuthinta lasetshenziswa iminyaka eminingi. Kodwa ngokuhamba kwesikhathi, izinga nsimbi saphela ukwanelisa izidingo zomuntu. Nge ukukhiqizwa umbuzo kwaba indlela yokwenza uzibuthe namandla nokuthi athembeke. Baqala ukuvela kancane kancane yokukhiqiza ubuchwepheshe odonsa yokufakelwa.

Wake wacabanga yini ukuthi indlela yokwenza ukhange? kungakhathaliseki ukuthi ekhiqizwa kuphela efektri, noma mhlawumbe ukwakha indlela bakudala? Kulesi sihloko, ake sixoxe indlela yokwenza uzibuthe ekhaya.

Ake siqale, njengoba besho, kusukela isitofu. Zonke izinto okungenani ibe ezinye ikhono magnetization, kukhona amandla kazibuthe noma ngokudonseka. Yiziphi amagama idatha? izakhiwo Okokuqala ukulahlekelwa kunalokho ngokushesha ukuheha izinto, kanti eyesibili - uwagcine, futhi, njengoba umthetho, isikhathi eside. Ngaphambi indlela yokwenza uzibuthe for okwenza kudingeke ukhethe impahla kwesokudla. Njengoba singabona kusukela ngenhla, hhayi zonke izinto ngenxa kulendlela.

Uma sithatha uzibuthe onamandla futhi uyibambe kubha metal ke lokhu kwanele magnetize isihloko. Futhi, uma ngokuphindaphindiwe ovulekile futhi vala ngokushesha okukhulu sikelo steel, banalo impahla edonsa izinto ezincane metal. Futhi atholwe impahla ingasetshenziswa ngokuphindaphindiwe, ukuze, isibonelo, ukuba uphume ayangena ezincane izingxenye steel.

Ngokuvamile, uzibuthe unomphela, okuyinto esenziwa magnetizing ucezu yensimbi, eside hhayi ngakho igcina impahla yayo. Njengomthetho, kwanele ukuba ukushisa lokushisa ethile noma hit kunoma iyiphi eqinile - kanye ngaphezulu ngeke ukudweba noma yini.

I izakhiwo kazibuthe ukushintsha ne ukwengeza isizinda compounds ezithile. Lawa izithasiselo okuyinto ukuguqula yensimbi ku steel. Lezinsimbi ezingaba lukhuni, ngokuvamile izinto kanzima kazibuthe, futhi ngaleyo ndlela kungase kube indaba kokuqala ukwakha uzibuthe. Ngokuvamile, insimbi engagqwali akakwazi lukhuni futhi izakhiwo ayizange ukuheha izinsimbi.

Manje ngqo asondele umbuzo: indlela yokwenza ukhange? Akunzima kangaka. Indlela yokwenza uzibuthe onamandla? Ukuze wenze lokhu uzodinga: isigaxa steel lukhuni futhi inductor. On usayizi ucezu steel kufanele kube njengokuthola kufanelekile ngokuphelele ngaphakathi esondweni yakho. Uma zamanje osebenzisa ngayo - kusukela kunethiwekhi, ujike fuse wesifunda ukuvimbela Ukunciphisa isekhethi.

yensimbi noma steel Akukhona nje isetshenziselwa ukunikeza impahla ndaba ukuheha izinsimbi. Ngenxa yale njongo kwesinye isikhathi kungathatha alnico - ingxubevange ekhethekile eyenziwe kusukela izinsimbi eziningana. Kodwa kuvame kakhulu ukuba kusetshenziswe le njongo ferrites. Ferrites kukhona yensimbi oxides in ifomu powder, okuyinto exutshwe izithasiselo ezithile. It odonsa ferrite kukhona elula kakhulu, angase bayicabange ukuma. Nokho, anamandla kakhulu yilezo odonsa, eyayibonakala wawenziwa ngengxube olukhethekile neodymium, lensimbi nangomthofu boron.
