Zinc in nɔ-magnɛtik nature na valyu insay difrɛn aplikeshɔn dɛn, mɔ usay dɛn fɔ avɔyd magnɛtik intafɛreshɔn. Frɔm kɔrɛshɔn-rɛsistant kɔtin to ilɛktromagnetik shild insay ilɛktroniks, Zinc in yon prɔpati dɛn mek am indispɛnsabl insay mɔdan industri.
Ɔndastand di nɔ-magnɛtik karakta we Zinc nɔ jɔs mek, klia wan kɔmɔn miskɔnsɛpshɔn bɔt i de sho bak di impɔtants fɔ difrɛn matirial prɔpati dɛn na tɛknɔlɔji ɛn day kastin manufakchurin.
1. Wetin na zink ɛn wetin na magnetism .
Zinc, we na bluish-wayt mɛtal wit atɔmik nɔmba 30, de ple impɔtant pat pan difrɛn industri dɛn. Na Andreas Marggraf bin fɛn am insay in mɛtal fɔm insay 1746, i dɔn bi indispɛns na di mɔdan layf. Akɔdin to di US Geological Survey, di global zinc prodakshɔn bin rich lɛk 13.2 milyɔn mɛtrik tan insay 2020, we sho in impɔtants na di industrial wɔl.
Fɔ ɔndastand di magnɛtik prɔpati dɛn fɔ di matirial dɛn impɔtant fɔ bɔku aplikeshɔn dɛn, frɔm ɛvride gadget dɛn to kɔt-ɛj tɛknɔlɔji dɛn. As wi de delv insay Zinc in rilayshɔn wit magnetism, wi go uncover fascinating insights bɔt dis versatile element ɛn in yunik ples insay di periodik tebul.
2. Zinc in magnɛtik nature .
2.1 Di klasifikasiɔn fɔ di zink
Zinc de insay di kategori fɔ di dayagnɛtik matirial dɛn. Dis klasifikasiɔn kin saund kɔmpleks, bɔt i jɔs min se zink de sho wik ripulshɔn we dɛn de ɛkspos to magnɛtik fil dɛm. Di dayagnɛtik prɔpati fɔ zink na kwantifay bay in magnɛtik susɛptibiliti, we na lɛk -1.56 × 10⁻5 (dimɛnshɔnlɛs SI yunit dɛn) na rum tɛmpracha.
2.2 Magnɛtik Rispɔns .
we dεn put di zink in rεspכns to wan ekstenal magnεtik fil, di rεspכns fכ di zink de rili difrεnt frכm wetin wi de obsכv insay kכmכn magnεtik mεtirial dεm lεk ayn. Insted fɔ mek dɛn atrak, zink wik wan push away frɔm di magnɛtik sɔs. Dis bihayvya kin sho tru di Faraday we, usay wan smɔl pat pan zink we wan tin trɛd go stɔp go smɔl smɔl we dɛn briŋ wan strɔng magnet nia am.
Fɔ sho dis biɛvhɔ, tink bɔt di tebul we de dɔŋ ya we yu kɔmpia di magnɛtik susɛptibiliti dɛm:
| Material Tayp | Magnɛtik Susceptibility (χ) | ɛgzampul dɛm |
| Fɛromagnetik . | Big pɔsitiv (>1000) | ayɛn (χ ≈ 200,000) . |
| Paramagnetik . | Smɔl pɔsitiv (0 to 1) . | aluminium (χ ≈ 2.2 × 105557) |
| Dayagnɛtik . | Smɔl negatif (-1 to 0) . | Zinc (χ ≈ -1,56 × 10⁻5) |
3. Wetin mek Zinc nɔto magnɛtik .
3.1 Atɔmik strɔkchɔ fɔ zink .
Zinc in lack of magnetic properties kin tray bak to in ilektron konfigyushɔn. di arenjmεnt fכ εlektrכn dεm na di zink in כta sεl de ple wan imכtant rol fכ no in magnεtik bihayv.
Zinc in ilɛktron kɔnfigyushɔn na [AR]3D⊃1;⁰4S⊃2;. Dis min se ɔl di zink in ilɛktrɔn dɛn de pe, we nɔ de lɛf ɛni ɛliktrɔn we nɔ gɛt pe na in ɔtamost ɔrbital. di absכns fכ εlektrכn dεm we nכ de pe na di ki fכ כndastand wetin mek zink nכ de sho magnεtik prכpati.
Fɔ imajin dis, lɛ wi kɔmpia Zinc in ilɛktron kɔnfigyushɔn wit di wan we wan magnɛtik ɛlimɛnt:
| ɛlimɛnt | ilɛktron kɔnfigyushɔn | nɔ pe ɛliktrɔn dɛn |
| Zinc na di . | [ar]3d⊃1;⁰4S⊃2; | 0 |
| Ayɛn | [AR]3d⁶4S⊃2; | 4 |
3.2 Magnɛtik mɔnt na zink .
Due to in fuli paired electrons, zinc get magnetic moment of zero. Dis difrɛn bad bad wan wit fɛromagnɛtik matirial dɛn lɛk ayɛn, we gɛt ɛliktrɔn dɛn we nɔ gɛt pe we kin alaynɛd insay magnɛtik fil, we kin mek wan nɛt magnɛtik mɔnt.
Di magnɛtik mɔnt (μ) fɔ wan atɔm kin kɔl bay we dɛn yuz di fɔmula:
μ = √[n(n+2)] μb .
usay n na di nɔmba fɔ di ɛliktrɔn dɛn we nɔ gɛt pe ɛn μB na di Bohr magnɛtɔn (9.274 × 10⁻⊃2;⁴ J/T).
Fɔ zink: n = 0, so μ = 0 fɔ ayɛn: n = 4, so μ ≈ 4.90 μb
4. Fakta dɛm we de afɛkt di magnɛtik prɔpati dɛm we de afɛkt di zink .
4.1 klin ɛn dɔti .
Pan ɔl we klin zink na dayamagnɛtik, sɔm tɛm dɛn kin gɛt dɔti tin dɛn we kin mek i nɔ gɛt bɛtɛ trɛnk. Sɔm impyuriti kin mek lokaliz magnɛtik mɔmɛnt, we kin mek dɛn gɛt wik paramagnɛtik bihayvya. Bɔt dis ifɛkt tipikul so smɔl dat i de kɔntinyu fɔ bi tin we nɔ go notis insay ɛvride aplikeshɔn dɛn.
Wan stɔdi we dɛn pul na di Jɔnal fɔ Magnɛtism ɛn Magnɛtik Matirial (2018) dɔn sho se di zink nanopartikl dɛn we dɛn dɔn dɔp wit 5% manganɛs sho wik fɛromagnetik bihayvya na rum tɛmpracha, wit wan satyuteshɔn magnɛtizayshɔn we na 0.08 emu/g.
4.2 Tɛmpratura .
Tεmpracha de ple bak wan rol insay di zink in magnεtik bihayv. As di tɛmpracha de go ɔp, ɛni magnɛtik ifɛkt we kin apin bikɔs ɔf di dɔti tin dɛn kin stɔp mɔ. Dis kin apin bikɔs tɛmal ɛnaji kin ambɔg di alaynɛshɔn fɔ ɛliktrɔn, we kin ridyus ɛni smɔl magnɛtik tɛndens.
Di rilayshɔn bitwin di tɛmpracha ɛn di magnɛtik susɛptibiliti fɔ dayagnɛtik matirial dɛn lɛk zink de fala Curie in lɔ:
χ = C / T .
We C na di Curie kɔnstant ɛn T na di absɔlɔb tɛmpracha. fכ zink, di tεmprachכ dipεndεns rili wik, wit chenj we less dan 1% ova wan tεmprachכ rεnj we de 100k to 300k.
5. zink kin bi magnet?
5.1 Alɔy .
Pan ɔl we Pure Zinc nɔ kin ebul fɔ bi magnɛtik, alɔy am wit fɛromagnɛtik matirial kin mek kɔmpawnd wit magnɛtik prɔpati. Fɔ ɛgzampul, dɛn kin yuz sɔm zink alɔy dɛn fɔ mek magnɛtik sɛns. I impɔtant fɔ no se dɛn alɔy ya de sho magnɛtik prɔpati bikɔs ɔf di ad ɛlimɛnt dɛn, nɔto zink insɛf.
