Demystifying Strong Magnets

Chii Chinopa Magnet Kushanda Kwayo Kwakasimba?

Kana nyanzvi dzehunyanzvi dzichiti magineti "yakasimba," hadziwanzo kubatanidzwa panhamba imwe chete kubva papepa rema spec. Simba remagineti rechokwadi rinobva mukubatana kwezvinhu zvakawanda mumamiriro ezvinhu chaiwo—uye ndiwo musanganiswa uyu unoparadzanisa mashandiro edzidziso nekushanda kwaunogona kuvimba nawo mukuita.

Zvinhu zvakasiyana-siyana zvakabatana zvinosarudza mashandiro chaiwo emagineti:

Chekutanga i remanence (Br), iyo inoyera magnetic flux inochengetwa nemagnet kana yabviswa mumunda wayo wemagnetizing. Funga nezvayo se "sticking base" yemagneti—kukwanisa kwayo kunamira pazvinhu zveferromagnetic kwenguva refu mushure mekunge maitiro ekutanga emagnetizi apera. Pasina remanence yakakwana, kunyange magineti yakagadzirirwa simba inotambura kuchengetedza kubata mukushandiswa kwezuva nezuva.

Chechipiri kumanikidzwa (Hc), chiyero chekuti magineti inodzivirira sei demagnetization kubva kudzvinyiriro dzekunze. Kumanikidzwa uku kunogona kubva pakusangana kweminda yemagineti (inowanzoonekwa munzvimbo dzemaindasitiri nematurusi akawanda) kusvika pakumanikidzwa kwekupisa kwenguva refu (senge munzvimbo dzemainjini kana nzvimbo dzekusvetera). Mukushandiswa uko kutadza kunogona kukanganisa mashandiro—senge michina yekurapa kana michina yekugadzira nemazvo—kumanikidzwa kwakanyanya hakusi kungowana bhonasi chete; chinodiwa chisingakurukurwi kuti uve nechokwadi chekuti mashandiro acho anoshanda nguva dzose.

Chechitatu chiri pamusoro ndicho chigadzirwa chesimba guru (BHmax), chiyero chinotsanangura huwandu hwesimba remagineti: zviri nyore, chinoyera kuti simba remagineti rinogona kuunganidzwa sei mukati mehukuru hwemagineti. Kukosha kweBHmax kwakakwira zvinoreva kubvisa simba rakawanda rekudhonza kubva kumagineti madiki uye akareruka—uye ichi chinhu chinochinja magadzirirwo apo nzvimbo iri pamutengo wepamusoro, senge zvishandiso zvemagetsi zvidiki kana zvikamu zvemotokari. Chiyero ichi chinobatanidza zvakananga nekushanda zvakanaka kwenyika chaiyo, zvakare: magineti ine BHmax yakasimba inobvumira mainjiniya kugadzira zvigadzirwa zvakatetepa, zviri nyore pasina kurasikirwa nesimba rinodiwa kuti basa riitwe. Zvinhu zvitatu izvi pamwe chete zvinoumba musimboti wekushanda kwemagineti mukushandiswa kwechokwadi—hapana inoshanda yoga, uye chiyero pakati pazvo ndicho chinosarudza kana magineti ichaita zvakanaka mubasa rayo rayo kana kuti ikatadza kusvika pachinangwa.

Kana ukaunganidza magineti ese anogara aripo nhasi, mhando dze neodymium dzinogara dzichionekwa kupfuura dzimwe nzira dzechinyakare dzakadai se ferrite ne alnico mukuyerwa uku kwese.

Sainzi Iri Kutungamira KweNeodymium?

Kubva pakatanga kushandiswa muma1980, magineti e neodymium akachinja mikana yekugadzira nzvimbo asi simba regineti harigone kukanganiswa. Kugona kwavo kunoshamisa kunobva mukati mehurongwa hwavo hwemaatomu:

Kurongeka kwakasiyana kwekristaro ye tetragonal muNdFeB kunogadzira izvo masayendisiti anodaidza kuti magnetocrystalline anisotropy. Mukutaura kwechokwadi, izvi zvinoreva kuti maumbirwo emukati memagnetic anorongeka nenzira yaanoda, zvichigadzira simba guru remunda.

Magineti aya anounza simba guru rekuchengetedza simba uye simba rekushandisa simba remagetsi, zvichiita kuti akwanise kuchengetedza simba remagetsi rakasimba uku achitsungirira kumanikidzwa kwesimba remagetsi. Kushanda kwakaringana uku kunobatsira zvikuru mukushandiswa kwesimba uko mamiriro ezvinhu asingawanzo gara akakwana.

Magineti eNeodymium anokunda zvikuru makwikwi eSamarium-Cobalt, Alnico, neFerrite. Kudzvanywa kwesimba uku kunoshamisa kunoita kuti zvikwata zveinjiniya zvigadzire mhinduro dzakatetepa uye dzinoshandisa simba shoma.

Nei Maumbirwo Akakombama Achishanda Zvakanaka?？

Magineti e rectangular neodymiumZvakaonekwa sezvinhu zvinofarirwa munzvimbo dzakasiyana-siyana uko kushanda zvakanaka kwenzvimbo kunofanira kuenderana nezvinodiwa pakushanda kwakasimba. Maitiro avo akafanana nebhuroko anopa mabhenefiti akawanda anooneka:

Nzvimbo dzakati sandara dzinoita kuti pave nekusangana kwakanyanya nezvinhu zvine simba remagetsi, zvichiita kuti pave nekunamatira kwakasimba kupfuura maumbirwo akakombama kana asina kurongeka.

Mitsetse yakachena nemakona akapinza zvinoita kuti zvive nyore kubatanidza michina yeindasitiri nemidziyo yevatengi, zvichiita kuti kuisa uye kugadzirisa zvive nyore.

Musika uyu une magineti e rectangular neodymium ane magiredhi akasiyana-siyana ekushanda (kazhinji N35 kusvika N52) pamwe chete nesarudzo dzakasiyana dzekupenda (senge nickel, zinc, uye epoxy) kuti agadzirise mamiriro akasiyana ekushanda.

Nzira Dzekugadzira Dzakatsanangurwa

Vagadziri vanowanzogadzira magineti e neodymium kuburikidza neimwe yenzira mbiri dzakagara dziripo:

Nzira yekunyungudutsa inotanga nekunyungudutsa zvinhu zvisina kugadzirwa, zvochichinja kuita upfu hwakatsetseka, zvobatanidzwa nemagnetic, zvozobva zvanyungudutsa uye zvogadzirwa nemazvo. Nzira iyi inoita kuti magnetic ishande zvakanaka asi inoda kudzora kwakasimba pakuumbwa kwezviyo zvidiki-diki panguva yekugadzirwa kwayo.

Kugadzirwa kwemagineti akabatana kunosanganisa zvidimbu zvemagineti nezvinobatanidza zvepurasitiki zvisati zvaumbwa. Magineti anobuda, kunyangwe asina kusimba uye achichinjika muchimiro, anowanzo ratidza simba shoma remagineti kana tichienzanisa neshanduro dzakagadzirwa nesimbi.

Kune magineti e rectangular neodymium, vagadziri vemaindasitiri vanonyanya kushandisa nzira dzekugadzira sintering nekuti nzira iyi inochengetedza saizi chaiyo uku ichivimbisa mhedzisiro yakafanana yepamusoro - zvinhu zviviri zvakakosha pakushandisa kwehunyanzvi.

Zvinhu Zvinokosha Zvinoshanda

Kunyange zvazvo mapepa ekugadzirisa achipa nhungamiro inobatsira, nzvimbo chaiyo yekuisa inounza zvimwe zvinoshanduka:

Magineti ekare e-neodymium anotanga kuora simba zvachose kana tembiricha yadarika 80°C. Pamamiriro ekudziya, vagadziri vanogadzira magiredhi akakosha anosanganisira zvinowedzerwa zvedysprosium kana terbium.

Magineti eNdFeB asina chinhu anoramba ari nyore kubatwa nengura nengura. Nzvimbo dzinodzivirira dzinoshanduka kubva pane dzimwe nzira dzekuwedzera kuenda kune zvinhu zvinodikanwa, kunyanya munzvimbo dzine hunyoro kana dzine makemikari.

Pasinei nesimba rayo remagineti, magineti e-neodymium anoratidza kuputsika kunooneka. Kubata kana kupwanya zvisina hanya panguva yekugadzirisa kunogona kukonzera kupwanyika kana kutsemuka, zvichiita kuti zviome kuisa nemaune.

Nzvimbo Dzakaedzwa dzeKushandisa

Kubatana kwakasimba kwesimba remagineti rinobuda uye dhizaini inoshanda zvakanaka inoita kuti magineti erectangular neodymium akwanise kushandiswa munzvimbo dzakawanda:
