Simba reMagineti Rinoyerwa Sei?

Magineti ave ari zvinhu zvinonakidza kwemazana emakore, zvichikwezva masayendisiti nevanhu vanofarira zvinhu zvakasiyana-siyana nekugona kwavo kushamisa kukwezva zvimwe zvinhu. Kubva patsono dzekambasi dzinotungamira vaongorori vekare kusvika kunzira dzakaoma dzetekinoroji yemazuva ano, magineti anoita basa rakakosha muhupenyu hwedu. Asi tingayera sei simba reizvi?minda yemaginetiTinoyera sei simba remagineti? Ngationgororei nzira nezvishandiso zvinoshandiswa kuyera simba remagineti.

Simba reMagineti

Simba remagineti rinonyanya kutsanangurwa nesimba rayo remagineti, nzvimbo yakatenderedza magineti uko simba rayo rinonzwikwa. Simba iri rinomiririrwa nemitsara yesimba, inotangira pamucheto wekuchamhembe wemagineti kusvika pamucheto wayo wekumaodzanyemba. Kana huwandu hwemitsara iyi hwakakura, simba remagineti rinosimbawo.

Gauss naTesla: Zviyero zveKuyera

Kuti vaone simba resimba remagineti, masayendisiti anoshandisa mayuniti maviri makuru ekuyera: Gauss naTesla.

Gauss (G): Ichi chidimbu chakatumidzwa zita renyanzvi yemasvomhu uye fizikisi yekuGermany Carl Friedrich Gauss, uye chinoyera huwandu hwemagnetic flux kana kuti magnetic induction. Gauss imwe chete yakaenzana neMaxwell imwe pa square centimeter. Zvisinei, nekuda kwehukuru hudiki hweGauss, kunyanya mumamiriro ezvinhu emazuva ano, masayendisiti anowanzo shandisa Tesla kuti awane simba guru remagnetic fields.

Tesla (T): Yakatumidzwa zita rekuremekedza muvambi wekuSerbia-America uye mainjiniya wemagetsi Nikola Tesla, chiyuniti ichi chinomiririra huwandu hwakakura hwemagineti kana tichienzanisa neGauss. Tesla imwe chete yakaenzana neGauss 10,000, zvichiita kuti ive chiyuniti chinoshanda zvakanyanya pakuyera masimba emagineti akasimba, akadai seaya anogadzirwa nemagineti ane simba anoshandiswa mukutsvagisa kwesainzi kana kushandiswa kwemaindasitiri.

Magnetometer

Magnetometers zvishandiso zvakagadzirirwa kuyera simba uye kutungamira kweminda yemagineti. Midziyo iyi inouya mumhando dzakasiyana-siyana, kubva pakambasi dziri nyore dzinobatwa nemaoko kusvika kumidziyo yemurabhoritari yakaoma. Heano mamwe marudzi akajairika emaginetometer anoshandiswa kuyera simba reminda yemagineti:

1. Magnetometer dzeFluxgate: Aya mamagnetometer anoshandisa misimboti ye electromagnetic induction kuyera shanduko muminda yemagineti. Anosanganisira imwe kana kupfuura magineti akakomberedzwa ne coils dzewaya. Kana akaiswa pamunda wemagineti, ma cores acho anova magineti, zvichikonzera chiratidzo chemagetsi mu coils, iyo inogona kuyerwa uye kugadziriswa kuti ione simba remunda wemagineti.

2. Magnetometer dzeHall Effect: Maginetometer eHall effect anoshandiswa paHall effect, iyo inotsanangura kugadzirwa kwemusiyano wevoltage (Hall voltage) pamusoro pemuchina wemagetsi kana waiswa pamagnetic field yakatarisana nekuyerera kwemagetsi. Nekuyera voltage iyi, maginetometer eHall effect anogona kuona simba remagnetic field.

3. Magnetometer dzeSQUID: Mamagnetometer eSuperconducting Quantum Interference Device (SQUID) ndemamwe emamagnetometer anonyanya kunzwa aripo. Anoshanda zvichibva pahunhu hwequantum hwemasuperconductors, zvichivabvumira kuona masimba emagineti asina simba zvakanyanya, kusvika padanho refemtoteslas (10^-15 Tesla).

Kuenzanisa uye Kugadzirisa

Kuti zvive nechokwadi chekuti zviyero zvakarurama, maginetometer anofanira kuenzaniswa zvakanaka uye kuenzaniswa. Kuenzanisa kunosanganisira kuenzanisa kubuda kweginetometer nesimba regineto rinozivikanwa kuti pave nehukama hwakatsetseka pakati pekuverengwa kwechishandiso uye kukosha kwegineto chaiyo. Kuenzanisa kunoita kuti zviyero zvinotorwa nemaginetometer akasiyana zvienderane uye zvienzane.

Mashandisirwo eMagnetometry

Kukwanisa kuyera simba remagineti nemazvo kune mashandisirwo akawanda muminda yakasiyana-siyana:

Fizikisi yezvepasi: Magnetometers anoshandiswa kudzidza simba remagineti rePasi, iro rinopa ruzivo rwakakosha nezvemaumbirwo uye maumbirwo emukati mepasi.

Kufamba: Kambasi, rudzi rwemagnetometer, yave iri maturusi akakosha ekufambisa kubva kare, ichibatsira vafambisi vengarava nevaongorori kuwana nzira yavo yekuyambuka makungwa makuru.

Sainzi YezvinhuMagnetometry inoshandiswa kutsanangurazvinhu zvemaginetiuye kudzidza hunhu hwadzo, hunokosha pakugadzirwa kwetekinoroji dzakadai semidziyo yekuchengetera magineti uye michina yekufungidzira magineti (MRI).

Kuongorora Muchadenga: Magnetometers dzinoiswa muzvitundumuseremusere kuti dzidzidze minda yemagineti yemitumbi yekudenga, zvichipa ruzivo rwekuumbwa kwayo uye nhoroondo yezve geology.

Mhedziso

Kuyera simba remagineti kwakakosha pakunzwisisa maitiro emagineti uye mashandisirwo awo munzvimbo dzakasiyana siyana. Kuburikidza nemayuniti akadai saGauss naTesla uye zvishandiso zvakaita semagnetometers, masayendisiti anogona kuyera simba remagineti nemazvo, zvichigadzira nzira yekufambira mberi mune tekinoroji, kutsvaga, uye kutsvagisa kwesainzi. Sezvo kunzwisisa kwedu kwemagnetism kuchiramba kuchikura, saka kugona kwedu kushandisa simba rayo kuti vanhu vabatsirwe.
