Gupima Imiterere ihoraho ya Magneti

Ikizamini gihoraho cya Magneti: Icyerekezo cya tekinike

Akamaro ko gupima neza
Niba ukorana nibikoresho bya magneti, uzi ko imikorere yizewe itangirana no gupima neza. Amakuru dukusanya mugupima magnet agira ingaruka zitaziguye mubyemezo byubwubatsi bwimodoka, ibikoresho bya elegitoroniki, abaganga, tekinoroji yubuvuzi, hamwe ningufu zishobora gukoreshwa.

Ibipimo bine byingenzi
Iyo dusuzumye magnesi zihoraho muri laboratoire, mubisanzwe tureba ibintu bine byingenzi bisobanura ubushobozi bwabo:

Br: Kwibuka kwa Magneti
Gusigara (Br):Gereranya iyi nka "memoire" ya magneti ya magnetism. Tumaze gukuraho umurima wa magnetiki wo hanze, Br iratwereka uburyo ubukana bwa magnetique ibintu bigumana. Ibi biduha ibyingenzi imbaraga za magneti mugukoresha nyabyo.

Hc: Kurwanya Demagnetisation
Guhatira (Hc):Tekereza kuri ibi nka "ubushake" bwa magneti - ubushobozi bwayo bwo kurwanya demagnetisation. Ibi tubigabanyijemo muri Hcb, itubwira umurima uhinduka ukenewe kugirango duhagarike ibisohoka bya magneti, na Hci, byerekana uburyo umurima ukomeye dukeneye gusiba burundu guhuza imbere kwa magneti.

BHmax: Ikimenyetso Cyimbaraga
Ibicuruzwa ntarengwa (BHmax):Numubare wuzuye imbaraga dukuramo muri hystereze. Yerekana ingufu nyinshi yibikoresho bya magneti bishobora gutanga, bigatuma tujya murwego rwo kugereranya ubwoko butandukanye bwa magneti hamwe nurwego rwimikorere.

Hci: Guhagarara mukibazo
Guhatira Imbere (Hci):Kuri uyumunsi imikorere-ikomeye ya NdFeB, iyi niyo gukora-cyangwa kumena. Iyo indangagaciro za Hci zikomeye, rukuruzi irashobora kwihanganira ibihe bibi - harimo ubushyuhe bwo hejuru hamwe no kurwanya imirima ya magneti - nta gutakaza imikorere ikomeye.

Ibikoresho by'ingenzi byo gupima
Mubikorwa, twishingikiriza kubikoresho byihariye kugirango dufate iyi mitungo. Hysteresisgraph ikomeza kuba laboratoire yacu ya laboratoire, igashushanya umurongo wuzuye wa BH ukoresheje uburyo bwo kugenzura ibintu. Ku igorofa, dukunze guhinduranya ibisubizo byoroshye nka salle ya salle ya salle cyangwa Helmholtz coil kugirango igenzurwe vuba.

Gupima Magneti Yifatanije
Ibintu bigenda byoroha cyane mugihe tugeragezaadhesive-ushyigikiwe na neodymium magnesi. Ibyoroshye byubatswe byubatswe bizana ibibazo bimwe byo kugerageza:

Ibibazo
Ibibazo byo gukemura:Urwo rufatiro rusobanura rukuruzi ntizigera yicara neza muburyo busanzwe bwo kugerageza. Ndetse na microscopique yo mu kirere irashobora kugoreka ibyo dusoma, bisaba ibisubizo bihanga kugirango dushyireho neza.

Ibitekerezo bya Geometrie
Ibitekerezo bifatika:Kamere yabo yoroheje, yunamye isaba guhuza ibicuruzwa. Igenamiterere risanzwe ryagenewe gukumira gusa ntirikora mugihe icyitegererezo cyawe gishobora guhinduka cyangwa kidafite ubunini bumwe.

Kugerageza Ibisabwa Ibidukikije
Ibisabwa bya Magnetique Ibisabwa:Kimwe no gupima magnetiki yose, tugomba kuba abafana kubijyanye no kugumisha ibintu hafi ya magnetiki hafi. Mugihe ibifata ubwabyo bidafite aho bibogamiye, ibikoresho byose byuma byegeranye cyangwa izindi magneti bizabangamira ibisubizo byacu.

Kuki Ikizamini Cyingenzi？
Umubare wo kwipimisha neza ni muremure. Twaba twujuje ibisabwa kugirango dukoreshe ibinyabiziga byamashanyarazi cyangwa ibikoresho byo gupima ubuvuzi, nta mwanya wo kwibeshya. Hamwe nubwoko bushigikiwe nubwoko, ntabwo turimo kugenzura imbaraga za rukuruzi gusa - turimo kugenzura niba ubushyuhe bwumuriro, kubera ko igiti gifatika akenshi cyananirana mbere ya magneti ubwayo mubihe by'ubushyuhe bwo hejuru.

Urufatiro rwo kwizerwa
Umunsi urangiye, kwipimisha neza ntabwo ari igenzura ryiza gusa - ni ishingiro ryimikorere iteganijwe muri buri porogaramu. Amahame shingiro agumaho muburyo bwa magneti, ariko abatekinisiye bajijutse bazi igihe cyo guhuza uburyo bwabo kubibazo bidasanzwe nkibishushanyo mbonera bifatika.
