Ndeupi misiyano pakati pemagineti redunhu uye maitiro emuviri eiyo magineti yakasimba

Misiyano mikuru pakati pemagineti redunhu uye redunhu zvemuviri zvivakwa ndezvizvi:
(1) Pane zvakanaka conductive zvinhu muzvarirwo, uye kune zvakare zvinhu zvinodzivirira ikozvino. Semuenzaniso, iyo resistivity yemhangura ndeye 1.69 × 10-2qmm2 / m, nepo iyo yerabha ingangoita kagumi izvo. Asi kusvika ikozvino, hapana chinhu chakawanikwa kuti chivhare magineti flux. Bismuth ine yakaderera permeability, inova 0. 99982μ. Iyo permeability yemhepo ndeye 1.000038 μ. Saka mweya unogona kutorwa sechinhu chine yakaderera permeability. Iyo yakanakisa ferromagnetic zvinhu zvine hukama permeability inosvika gumi kusvika kune yechitanhatu simba.

(2) Ikozvino ndiko kuyerera kwezvimedu zvinochajiswa mukondakita. Nekuda kwekuvapo kwekupokana kwekondukita, simba remagetsi rinoshanda pazvimedu zvinochaja uye rinopedza simba, uye kurasikirwa kwesimba kunoshandurwa kuita simba rekupisa. Iyo magineti inoyerera haimiriri kufamba kwechero chidimbu, uye haimiriri kurasikirwa kwesimba, saka kuenzanisa uku hakudiwi. Dunhu remagetsi uye redunhu remagineti zvakapatsanurwa, imwe neimwe iine bundle rayo remukati. Kurasikirwa, saka kuenzanisa kwakaremara. Dunhu uye dhigirii remagineti zvakabatana, imwe neimwe iine chirevo chayo chisina mubvunzo chemuviri.

Magnetic maseketi akasununguka:
(1) Hakuzove nekuputsika kwedunhu mumagetsi edunhu, magineti flux iri kwese kwese.
(3) Magnetic maseketi anenge agara asina mutsara. Ferromagnetic kusada zvinhu hakuna mutsara, kusada kwemhepo kune mutsara. Iyo magnetic circuit ohm's mutemo uye kusada pfungwa dzakanyorwa pamusoro ichokwadi chete mumutsara wemutsara. Naizvozvo, mukugadzira kunoshanda, bH curve inowanzoshandiswa kuverenga nzvimbo yekushanda.
(2) Sezvo pasina zvachose isiri-magineti zvinhu, iyo magineti inoyerera haina kumanikidzwa. Chete chikamu cheiyo magineti flux inoyerera kuburikidza neyakatsanangurwa magineti wedunhu, uye imwe yese inopararira munzvimbo yakatenderedza magineti wedunhu, iyo inonzi magineti leakage. Kuverenga chaiko uye kuyerwa kweiyi magnetic flux leakage yakaoma, asi haigone kufuratirwa.
