Taariikhda iyo Taariikhda

Magnet-ka joogtada ahi waa qayb muhiim ka ah nolosha casriga ah. Waxaa laga helaa ama loo isticmaalaa in lagu soo saaro ku dhowaad kasta oo casri ah maanta. Magnet-kii ugu horreeyay ee joogtada ahaa waxaa laga soo saaray dhagxaan si dabiici ah u dhaca oo loo yaqaan hoyestones. Dhagxannadan waxaa markii ugu horraysay baranayey Shiinaha 2500 sano ka hor kadibna Giriiggu, kuwaas oo dhagxaanta ka helay gobolka Magnetes, kaas oo sheygan magaciisa laga helay. Wixii markaas ka dambeeyay, astaamaha qalabka magnet-ka si weyn ayaa loo wanaajiyey maantana maaddooyinka magnet-ka joogtada ahi waxay boqolaal jeer ka xoog badan yihiin magnet Qarniyadii hore. Ereyga magnet-ka joogtada ahi wuxuu ka yimaadaa awooda magnet-ka inuu qabto awood magnet laaluusho ka dib markii laga saaray aaladda magnetizing. Aaladaha noocan oo kale ah waxay noqon karaan kuwo kale oo xoog leh oo Magnetized joogto ah, elektro-magnets ama fiilooyin fiilo leh oo si kooban loogu xukumay koronto. Awooda ay u leeyihiin inay qaadaan awood magnetic ayaa ka dhigaysa inay waxtar u yeeshaan haysashada walxaha meesha, u beddela korantada awood ujeedo iyo dhanka kale (matoorrada iyo matoorrada), ama saamayntooda waxyaabaha kale ee agtooda ah.

Design

Waxqabadka magnetic-ka sareeya waa shaqo injineerida magnetic ka fiican. Macaamiisha u baahan kaalmaynta qaabeynta ama naqshadaha wareegga adag, QM's kooxdaada injineerro khibrad leh iyo injineer iibiyayaal aqoon korodhsi ayaa adeegaaga ku jira. QM Injineerada waxay la shaqeeyaan macaamiisha si ay u horumariyaan ama u ansaxiyaan naqshadaha jira iyo sidoo kale inay horumariyaan naqshado cusub oo soo saaraya saameyn magnetic gaar ah. QM Waxay soo saartaa naqshadaha magnetic-ga leh ee soo gudbiya si aad u xoog badan, unugyo ama dhulal magnetic gaar ah oo badiyaa beddela kuwa waaweyn iyo kuwo aan fiicnayn oo naqshadaha magnet-ka iyo naqshada magnet joogto ah. Macaamiilku way ku kalsoon yihiin marka ay la yimaadaan fikrad adag ama fikrad cusub taas QM ayaa la kulmi doona caqabaddaas iyadoo laga soo qaatay 10 sano oo ah khibrad magnetic. QM wuxuu leeyahay dadka, waxsoosaarka iyo tikniyoolajiyadda birlabyada shaqada u horseeday inay shaqeeyaan.

Xulashada Magnet

Xulashada Magnet ee dhammaan codsiyada waa inay tixgeliyaan dhammaan wareegga magnetic iyo bay'ada. Halkee ay Alnico ku habboon tahay, baaxadda magnet waa la yareyn karaa haddii ay noqon karto mid magnetizing ka dib isu urursiga wareegga magnetic. Haddii loo isticmaalo si ka madax banaan qaybaha kale ee wareegga, sida codsiyada amniga, dhererka wax ku oolka ah ee cabirkiisu yahay dhexroor (oo la xiriira iskuxirka labada dhinac) waa inuu ahaadaa mid aad u weyn oo keenaya magnetku inuu ka shaqeeyo jilibka dusheeda wareega qalooca Quagnetization labaad. Codsiyada xasaasiga ah, Magn magnnetka Alnico ayaa laga yaabaa in lagu habeeyo qiimeynta aasaasiga ah ee cabirka qulqulaya cabirka.

A by-product of low coercivity is sensitivity to demagnetizing effects due to external magnetic fields, shock, and application temperatures. For critical applications, Alnico magnets can be temperature stabilized to minimize these effects  There are four classes of modern commercialized magnets, each based on their material composition. Within each class is a family of grades with their own magnetic properties. These general classes are:

  • Neodymium Iron Boron
  • Samarium Cobalt
  • dhoobada
  • Alnico

NdFeB and SmCo are collectively known as Rare Earth magnets because they are both composed of materials from the Rare Earth group of elements. Neodymium Iron Boron (general composition Nd2Fe14B, often abbreviated to NdFeB) is the most recent commercial addition to the family of modern magnet materials. At room temperatures, NdFeB magnets exhibit the highest properties of all magnet materials. Samarium Cobalt is manufactured in two compositions: Sm1Co5 and Sm2Co17 - often referred to as the SmCo 1:5 or SmCo 2:17 types. 2:17 types, with higher Hci values, offer greater inherent stability than the 1:5 types. Ceramic, also known as Ferrite, magnets (general composition BaFe2O3 or SrFe2O3) have been commercialized since the 1950s and continue to be extensively used today due to their low cost. A special form of Ceramic magnet is "Flexible" material, made by bonding Ceramic powder in a flexible binder. Alnico magnets (general composition Al-Ni-Co) were commercialized in the 1930s and are still extensively used today.

Waxyaabahani waxay soo maraan guryo kala duwan oo u qalma baahiyo kala duwan oo dalabaadka ah. Waxyaabaha soo socdaa waxaa loogu tala galay in lagu bixiyo dulmar guud laakiin ficil ficil ah oo ku saabsan qodobada ay tahay in laga fiirsado marka la dooranayo qalabka ku habboon, darajada, qaabka, iyo cabirka magnetka ee barnaamij gaar ah. Shaxanka hoose wuxuu muujinayaa qiimayaasha caadiga ah ee astaamaha ugu muhiimsan ee heerarka xulasho ee walxaha kala duwan ee isbarbardhiga. Qiyamtan ayaa si faahfaahsan looga wada hadli doonaa qeybaha soo socda.

Daaweynta dusha

Magnets-ka waxay u baahan karaan daboolida iyadoo kuxiran dalabka loogu talagalay. Maaraduhu wuxuu kor u qaadaa muuqaalka, iska caabinta dillaaca, ka ilaalinta dharka oo laga yaabo inuu ku habboon yahay codsiyada xaaladaha qolka nadiifka ah.
Samarium Cobalt, Alaabada Alnico waa wax daciifa, mana u baahna in la isku daboolo ka-hortagga daxalka. Alnico si fudud ayaa loogu sifeeyaa tayada qurxinta.
Magacyada 'NdFeB' waxay si gaar ah ugu nugul yihiin daxalka waxaana badanaa loo ilaaliyaa habkan. Waxaa jira jaakado kala duwan oo ku habboon birlabyada joogtada ah, Ma aha dhammaan noocyada daahan inay ku habboonaan doonaan shey kasta ama joomatari magnet, iyo doorashada ugu dambeysa waxay ku xirnaan doontaa codsiga iyo jawiga. Ikhtiyaar dheeraad ah waa in guriga lagu hayaa magnet xirmo dibedda ah si looga hortago daxalka iyo dhaawaca.

Magnetization

Magnet joogto ah oo la bixiyo laba xaaladood, Magnetized ama aan lahayn magnetized, inta badan lama calaamadeeyo awooddeeda. Haddii adeegsaduhu u baahdo, waxaan ku calaamadayn karnaa polarity ahaan habka lagu heshiiyay. Marka la amrayo amarka, adeegsaduhu waa inuu ku wargaliyaa xaalada keenida iyo haddii calaamadda nambarka loo baahan yahay.

Meeraha magnetization ee magnet-ka joogtada ahi wuxuu la xiriiraa nooca wax magnetic magnetic joogto ah iyo xooggiisa qasabka ah ee maskaxda. Haddii birlabku u baahan yahay magnetization iyo demagnetization, fadlan nala soo xiriir oo weydii taageero farsamo.

Waxaa jira laba dariiqo oo lagu hagaajinayo magnet-ka: beerta DC iyo garaaca wadnaha magnetic.

Waxaa jira seddex qaab oo lagu baabi'inayo magnet-ka: duminta kuleylka waa farsamo hanaan gaar ah. demagnetization ee AC garoonka. Demagnetization ee garoonka DC. Tani waxay ku weydiisaneysaa dhul aad u xoog badan oo magnetic iyo xirfad sare u duminta.

Qaabka joomatari iyo jihada magnetization ee magnet joogtada ah: mabda 'ahaan, waxaan soo saareynaa magnet joogto ah qaabab kala duwan. Badanaa, waxaa ka mid ah baloog, disc, giraan, qeyb iwm. Sawirka faahfaahsan ee jihada magnetization-ka waa kan hoose:

Mabda'a nabdoonaanta ee hawlgalka buugga

1. Magnetized magnetized joogto ah oo leh magnetic xoog leh waxay soo jiidataa birta iyo arrimaha kale ee magnetic ku wareegsan si weyn. Xaaladda guud, hawlwadeenka buugga ayaa ah inay aad uga taxaddaraan si looga fogaado wixii dhaawac ah. Sababo la xiriira xoogga magnetic xoog leh, magnet weyn ee u dhow waxay qaadanayaan khatarta waxyeelada. Dadku had iyo jeer waxay u kalashaqeeyaan magnet-kan si gooni gooni ah ama qeylo. Xaaladdan oo kale, waa inaan kaydinaa galoofyada ilaalinta ee shaqeynaya.

2. Xaaladdan oo ah goob magnetic xoog leh, qayb walboo elektiroonig ah oo macquul ah iyo mitirka tijaabada waa la beddeli karaa ama dhaawici karaa. Fadlan iska ilaali in kombuyuutarka, soosaarida iyo warbaahinta magnetic, tusaale ahaan maqalka magnetic, cajaladda cajaladda maqalka iyo cajaladda fiidiyowga iwm, ay aad uga fog yihiin iskuulada magnetized, dheh wax ka badan 2m.

3. Isku dhaca ciidamada soo jiidanaya ee u dhexeeya labada magnet joogtada ahi waxay keenaysaa iftiin aad u weyn. Sidaa darteed, arrimaha ololi kara ama waxyaabaha qarxa waa inaan lagu ag dhigin hareerahooda.

4. Marka birlabka ay ku dhacdo sunta hydrogen, waa mamnuuc in la isticmaalo birlabyo joogto ah oo aan lahayn dabool daboolid. Sababta ayaa ah in sixirka hydrogen-ka uu burburin doono microilite-ka magnetka isla markaana horseedi doono burburka guryaha magnetic. Sida kaliya ee looga ilaalin karo magnetka wax ku oolka ah waa in ay ku xirnaato magnetka kiis isla markaana ay xirato.
