Kuyeza Makhalidwe Okhazikika a Magnet

Kuyesa Kwa Magnet Kwamuyaya: Kawonedwe ka Katswiri

Kufunika Koyezera Molondola
Ngati mumagwira ntchito ndi maginito, mumadziwa kuti ntchito yodalirika imayamba ndi kuyeza kolondola. Zomwe timapeza kuchokera pakuyezetsa maginito zimakhudza mwachindunji zisankho zaukadaulo wamagalimoto, zamagetsi ogula, ukadaulo wazachipatala, ndi kugwiritsa ntchito mphamvu zowonjezera.

Zinayi Zofunikira Zogwira Ntchito
Tikawunika maginito okhazikika mu labu, nthawi zambiri timayang'ana magawo anayi ofunikira omwe amatanthauzira kuthekera kwawo:

Br: Memory ya Magnet
Remanence (Br):Taganizirani izi ngati "memory" ya maginito ya magnetism. Titachotsa gawo lakunja la magnetizing, Br imatiwonetsa kuchuluka kwa maginito omwe zinthuzo zimasunga. Izi zimatipatsa maziko a mphamvu ya maginito pakugwiritsa ntchito kwenikweni.

Hc: Kukana kwa Demagnetization
Kukakamiza (Hc):Ganizirani izi ngati "willpower" ya maginito - kuthekera kwake kukana demagnetization. Timaphwanya izi kukhala Hcb, yomwe imatiuza gawo lakumbuyo lomwe likufunika kuti tiletse kutulutsa kwa maginito, ndi Hci, yomwe ikuwonetsa kuti ndi gawo lamphamvu bwanji lomwe timafunikira kufafanizira kulumikizana kwamkati kwa maginito.

BHmax: Chizindikiro cha Mphamvu
Maximum Energy Product (BHmax):Iyi ndi nambala yodzaza mphamvu yomwe timakoka kuchokera ku hysteresis loop. Imayimira mphamvu yayikulu kwambiri yomwe maginito imatha kupereka, ndikupangitsa kuti ikhale njira yathu yofananira mitundu yosiyanasiyana ya maginito ndi magwiridwe antchito.

Hci: Kukhazikika Pansi pa Kupanikizika
Intrinsic Coercivity (Hci):Kwa maginito amasiku ano a NdFeB omwe amagwira ntchito kwambiri, uku ndiye kupanga-kapena-break specifications. Makhalidwe a Hci akakhala amphamvu, maginito amatha kupirira zovuta - kuphatikiza kutentha kwambiri komanso kuthana ndi maginito - popanda kuwonongeka kwakukulu.

Zida Zoyezera Zofunika
M'malo mwake, timadalira zida zapadera kuti tigwire zinthuzi. Hysteresisgraph imakhalabe ngati kavalo wathu wa labotale, kupanga mapu amphumphu wathunthu wa BH kudzera mumayendedwe oyendetsedwa ndi maginito. Pansi pafakitale, nthawi zambiri timasinthira ku mayankho onyamula ngati ma Hall-effect gaussmeters kapena ma coils a Helmholtz kuti atsimikizire mwachangu.

Kuyesa Zomatira-Backed Magnets
Zinthu zimakhala zovuta kwambiri tikamayesazomatira-backed neodymium maginito. Kusavuta kwa zomatira zomangidwira kumabwera ndi zovuta zina zoyesa:

Zovuta Zokonzekera
Kuyika Mavuto:Chomatacho chimatanthawuza kuti maginito sakhala bwino bwino pamayeso oyeserera. Ngakhale mipata yaying'ono yowoneka bwino imatha kusokoneza kuwerenga kwathu, zomwe zimafunikira njira zopangira kuti muyike bwino.

Malingaliro a Geometry
Kuganizira za Fomu:Chikhalidwe chawo chowonda, chopindika chimafuna kukonzedwa mwachizolowezi. Kukhazikitsa kokhazikika komwe kumapangidwira midadada yolimba sikumagwira ntchito ngati mayeso anu amatha kusinthasintha kapena alibe makulidwe ofanana.

Kuyesa Zofunika Zachilengedwe
Zofunikira za Magnetic Isolation:Monga kuyesa konse kwa maginito, tiyenera kukhala otengeka posunga chilichonse chomwe sichikhala ndi maginito pafupi. Ngakhale zomatira palokha sizilowerera ndale, zida zilizonse zachitsulo zapafupi kapena maginito ena angasokoneze zotsatira zathu.

Chifukwa Chake Kuyesa Kuli Kofunika??
Zolinga zoyesa zolondola ndizambiri. Kaya tikuyenerera maginito oyendetsa galimoto yamagetsi kapena zida zowunikira zamankhwala, palibe cholakwika. Ndi mitundu yomatira kumbuyo, sikuti tikungoyang'ana mphamvu ya maginito - tikutsimikiziranso kulimba kwamafuta, chifukwa zomatira nthawi zambiri zimalephera maginito pawokha pamatenthedwe apamwamba kwambiri.

Maziko a Kudalirika
Pamapeto pa tsiku, kuyesa kwamphamvu kwa maginito sikungoyang'ana khalidwe - ndi maziko a ntchito zodziwikiratu pa ntchito iliyonse. Mfundo zazikuluzikulu zimakhala zofanana pamitundu yonse ya maginito, koma akatswiri anzeru amadziwa nthawi yosinthira njira zawo zamilandu yapadera ngati mapangidwe omata.
