Nyanzvi yesainzi yekuFrance Andre Marie Ampère (1775–1836) akataura nezvehukama huripo pakati pemagetsi anoyerera nepakati pechero dhayamita nesimba remagineti rinogadzirwa rakaripoteredza. Uyu ndiwo Mutemo waAmpère. Equation iri pazasi inoratidza mutemo waAmpère.

Huwandu hwe (Σ) zvikamu zvesimba remagineti (B) hwakafanana nehurefu hweyuniti yemutyairi, huchipeta hurefu hweyuniti yemutyairi (∆l), hwakaenzana nechibereko che µ o (µ o = 4π x 10 -7 Tm/A) uye magetsi (I).
Magetsi anoyerera nepawaya anogadzira simba remagineti rakaipoteredza. Kana waya yacho yakatwasuka, mitsetse yesimba remagineti inoita denderedzwa, waya yacho yakatwasuka iri pakati pedenderedzwa.
Kana paine waya mbiri dzakatwasuka dzakafanana uye dzakaparadzaniswa nedaro reL, saka simba remagineti rinogadzirwa nemagetsi ari muwaya yekufambisa 1 rinonzwikwa muwaya yekufambisa 2, saizvozvowo simba remagineti rinogadzirwa nemagetsi ari muwaya yekufambisa 2 rinonzwikwa muwaya yekufambisa 1.
topic Simba remagetsi, chaji yemagetsi, simba remagineti, simba magineti varumeTsanangura kuti magetsi anogona kugadzira simba remagineti. Kana magetsi emagetsi akafamba nepawaya refu, yakatwasuka, simba remagineti rinogadzirwa, nemitsara yemagetsi inoita denderedzwa yakatenderedza waya iri pakati. Mufananidzo uri kurudyi unoratidza izvi.
Muna 1819, musayendisiti wekuDenmark ainzi Hans Christian Oersted (1777–1851) akawana hukama huripo pakati pemagineti nemagetsi , kana kuti machaji anofamba . Akawana kuti kana tsono yekambasi iri pedyo newaya inotakura magetsi, yaitsauka. Kana pasina magetsi, tsono yekambasi yaitarisa kuchamhembe.
Tsono yekambasi imagneti, saka simba remagineti rinogona kuifambisa . Simba remagineti (F) rinobva kupi? Pedyo netsono yekambasi pane waya inotakura magetsi, saka magetsi emagetsi anofanira kugadzira simba remagineti.
Tarisa mufananidzo uri kurudyi. Shandisa mutemo wekurudyi kuti uone divi remagetsi emagetsi uye divi remagetsi emagetsi. Kana magetsi emagetsi (I) akakwira kumusoro, divi remagetsi emagetsi (B) richava sezvakaratidzwa pamufananidzo uri kuruboshwe. Kusiyana neizvi, kana magetsi emagetsi akadzika, divi remagetsi emagetsi richava sezvakaratidzwa pamufananidzo uri kurudyi.
