The conductors ari yemagetsi munda

Various muviri, sokuziva, rakakamurwa nonconductors (dielectrics) uye conductors dzavo magetsi ehupfumi. Chimwe zvinhu zvine conductors zviri wemagetsi munda, ndiko kuti mhosva dziri zvakanyatsoenzana pamusoro pemvura yaro, mukati izvo yemagetsi munda vasipo. How kutsanangura izvi?

The ndechokuti conductors vane chaiwo magetsi mhosva. Saka, simbi yakadai mhosva vari vatakuri akadai maerekitironi izvo kuzoonana navo maatomu. Dzinonzi akasununguka maerekitironi.

maerekitironi wakadai kondakita nesimbi, anoiswa mukati yemagetsi minda, achifuridzirwa dzesango simba kuchaita mugwara pakatarisana yemagetsi kusango nesimba.

Tora inotungamirira kuna ABCD yemagetsi munda, iri akaisa yunifomu munda, nesimba, kubva kuruboshwe kuenda kurudyi.

Pamusoro pemvura AC kondakita kunoitika zvakawandisa akaipa nokuchengeta, uye kunyanyisa akanaka - mumwe db. In muenzaniso uyu tinoona kuti tambo iri yemagetsi musango vari yakafadza. Zvaipomerwa kuti rionekwe kuti muitisi, ndinosika wokuwedzera yemagetsi munda mukati maro. Its munda mitsetse kuva negwara panyaya akarongwa zvikuru munda. Somugumisiro, makakatanwa pasi munda ari kondakita ipfupi, i.e., Kunoderedza simba kuti anoita vakasununguka maerekitironi, uye anoita sangano ravo. Zvaipomerwa kuti vari conductors ari wemagetsi munda, sangano achamira apo Pamusana munda simba mukati kwavari anova razero.

Saka, apo pakuenzanisa mhosva pamusoro muitisi mukati munda chisipo. Its Kusavapo inogona kushandiswa kudzivirira muviri kubva zvinokonzerwa kwokunze yemagetsi munda. Nokuti chinangwa ichi zvakakwana kumukomberedza mutumbi nhete conductive layer semuenzaniso, kuiisa simbi bhokisi. Inside mubhokisi rino minda haachazovipo.

Kuti aratidze kuti ari kupomerwa kondakita hapana yemagetsi munda, mune zvakaitika, Faraday akavaka waya huru mumakeji, iyo yakaiswa pamusoro insulators uye recharged. Kuva mukati muchitokisi pamwe hypersensitive electroscope, Faraday akaratidza kuti mukati hakusi chero zvemagetsi simba, kunyange zvazvo pfungwa rokunze pamusoro iri chaizvo mutariri. Fani iyi inonzi magetsi ne simba kana electrostatic induction. chikonzero chacho - mugumisiro nechitarisiko yemagetsi munda pamusoro maerekitironi iri kondakita dzisingafambwi. Uye mhosva zvine conductors mu wemagetsi munda, yainzi vakafurira mhosva.

Kuburikidza simba magetsi Fani anotsanangura kukwezvana pakati yakafadza uye nenaelektrizovannymi miviri, uyewo kuchinjwa zvemagetsi vebasa kuonana miviri.

Apo yakafadza muviri anouya nyore kondakita ipapo kuoneka payo vafurira mhosva zvose nezviratidzo. Saka, madzoro pakatarisana chiratidzo chichapiwa mwoyo muviri, uye kufanana mhosva vachagara dzinga. Nekuti akafanana mhosva vari kudivi chiedza kondakita, zvikuru kure kubva mumuviri, Pamusana mauto aya maviri ndiwo simba kukwezvana. Achifuridzirwa simba iri chiedza muitisi uchifarira muviri. Munguva kuonana of vakafurira mutariri ane pakatarisana chiratidzo chichapiwa neutralized nokuda kufurira mutariri chikamu chiri nahwo ari zvikuru. On chiedza kondakita inoramba chiratidzo chete muripo, uye muviri.

Nokuti kuti chiedza kondakita zvino ane mhosva dzakafanana muviri, zvichaita ariswededze mariri; chii tichengete experimentally.

Conductors uye dielectrics ari yemagetsi munda vane ehupfumi zvakasiyana. Saka, dielectrics vane chinenge hapana vakasununguka mhosva. Kana kuiswa yemagetsi mumunda polarization chinonakidza kunoitika.
