Metals uas tsis nyiam Magnets Hauv lawv lub xeev ntuj, cov hlau xws li txhuas, tooj dag, tooj liab, kub, txhuas thiab nyiaj tsis nyiam cov hlau nplaum vim tias lawv yog cov hlau tsis muaj zog. Txawm li cas los xij, koj tuaj yeem ntxiv cov khoom xws li hlau lossis hlau rau cov hlau tsis muaj zog kom ua rau lawv muaj zog.
Pob hlau nplaum lo rau hlau?
Hlau uas nyiam cov hlau nplaum
Cov hlau uas ib txwm nyiam rau cov hlau nplaum yog hu ua ferromagnetic hlau; cov hlau nplaum no yuav ruaj khov rau cov hlau no. Piv txwv li, hlau, cob alt, hlau, npib tsib xee, manganese, gadolinium, thiab lodestone yog tag nrho cov hlau ferromagnetic.
Puas hlau nplaum ua haujlwm ntawm txhuas?
Cov lus teb zoo tshaj yog hais tias txhuas tsis yog hlau nplaum raws li qhov xwm txheej ib txwm muaj. Qhov no yog vim aluminium cuam tshuam nrog cov hlau nplaum Tsis tas li, thaum raug cov hlau nplaum muaj zog, txhuas tuaj yeem sib nqus me ntsis txawm tias nws tsis pom cov hlau nplaum nyob rau hauv ib txwm muaj.
Yuav ua li cas cov hlau nplaum tsis lo?
Magnetic metals
Iron is magnetic, yog li tej hlau uas muaj hlau nyob rau hauv nws yuav tau attracted rau ib tug hlau nplaum. Hlau muaj hlau, yog li daim ntawv hlau steel yuav raug nyiam rau cov hlau nplaum ib yam nkaus. Feem ntau lwm yam hlau, piv txwv li txhuas, tooj liab thiab kub, tsis yog hlau nplaum. Ob lub hlau uas tsis yog hlau nplaum yog kub thiab nyiaj
Puas muaj dab tsi lo rau txhuas?
Cyanoacrylate - tseem hu ua instant adhesives, super kua nplaum, vwm kua nplaum, ca kua nplaum, thiab lwm yam. Rau lub zog siab heev siv cov hlau nplaum xws li 170 lossis 910® thawj. … Ob tug epoxies kuj tsim muaj zog bonds rau txhuas.

Puas yog cov hlau nplaum ua los ntawm cov hlau nplaum?
Natural magnets muaj nyob rau hauv lub ntiaj teb thiab yog nplua nuj nyob rau hauv ib tug hlau ntxhia hu ua magnetite. Cov hlau nplaum uas tsim los ntawm tib neeg tau tsim nyob rau hauv ib lub chaw sim los ntawm kev noj cov hlau alloys thiab ua lawv kom haum rau tus nqi .
Puas yog cov hlau nplaum muaj zog dua li cov hlau nplaum ruaj khov?
Electromagnets muaj txiaj ntsig tseem ceeb ntawm kev tswj hwm lawv lub zog sib nqus - ob qho tib si los ntawm kev tig cov hlau nplaum rau lossis tawm thiab los ntawm kev kho qhov tam sim no. Lawv kuj tseem muaj rub lub zog ntau dua li cov hlau nplaum ruaj khov Qee qhov kev kwv yees tso cov hlau nplaum loj tshaj plaws ntawm 20 npaug zog dua li cov hlau nplaum ruaj khov .
Puas tag nrho cov nyiaj hlau puas lo rau cov hlau nplaum?
Nyiaj npib tiag tiag yuav lo; coated npib yuav tsis. Yog tias koj cov nyiaj xyoo 1944 steel tsis txuas nws tus kheej mus rau cov hlau nplaum, nws yuav yog ib lub nyiaj npib tooj liab coated hauv txheej nyias ntawm cov hlau thiab tsis yog hlau tiag tiag mus txog .
Koj puas tuaj yeem khov cov nplaum nplaum nplaum nplaum nplaum?
Yog, koj tuaj yeem khov cov nplaum nplaum nplaum nplaum rau ib ncig ntawm 3 lub hlis. Koj tuaj yeem khov cov nplaum nplaum nplaum nplaum nplaum uas tsis tau ci los yog ci uas txhais tau tias koj tuaj yeem khov cov khoom seem ntawm cov paj npleg.
Vim li cas ib yam khoom hlau tsis muaj hlau nplaum nyiam rau cov hlau nplaum?
Thaum cov hlau nplaum raug coj los ze rau cov khoom siv ferromagnetic yav dhau los uas tsis muaj hlau nplaum, nws ua rau cov hlau nplaum hauv zos ntawm cov khoom uas tsis zoo li cov ncej ze tshaj, ib yam li hauv. unmagnetized khoom rau cov hlau nplaum raws li daim duab hauv .
