At this time, influenced by the ideas of the mechanics of Isaac Newton(1642-1727), the physical phenomena were explained by forces. The observation of the phenomenon of induction showed that when the circuit was closed, the needle is moved to be perpendicular to the wire. On the other hand, the same was true when the circuit was closed, but the direction of the electric current was reversed. In this case, the direction of needle movement is reversed. So Oersted found that a force perpendicular to the wire appeared as existed electrical current passing through it. Why the magnetic pole of the needle tended to revolve around the thread? What had in common electricity and magnetism? What was not understood? To perform their experiment Faraday, wire wrapped on two sides of a soft iron core. In a thread he called a battery, and the other, a galvanometer, which is a device used to detect and measure electrical currents. Motivated by other experiments he conducted studies and by other scientists, including French An-DRE-Marie Ampere(1775-1836), Faraday believed that the passage of current in the wire connected to the battery to induce a current to be detected galvanometer. The text placed in sequence, translated by Dias (2004), presents a description of how Faraday built his experimental apparatus. It was a ring made of iron (sweet) loop with 7/8 inch thick and 6 inches in outside diameter. Several turns of copper wire were wound around a ring half, the turns being separated by cotton string and - there were three wire lengths, each about 24 feet long and they could be connected as an extension or only used as separate pieces, isolated from each other. Call that side of ring A. On the other side, but separated by an interval, was wound wire in two pieces together, accounting for approximately 60 feet in length, the direction being as one of the first turns, this side call B. (FARADAY. Quoted by DIAS, 2004, p. 44) The next diagram represents the experimental apparatus used by Faraday. Contrary to what he expected, Faraday noted that only appeared some effect on the galvanometer (side B) when opening or closing the switch circuit (A side). Faraday performed other experiments, but the result was always the same: only appeared some effect on the B side when electric current on side A was started or stopped, ie when the circuit side A was closed or open. Keeping the cir- closed circuit, nothing was observed on side B.

U ovom trenutku, pod utjecajem ideje mehanike Isaac Newton(1642-1727), fizikalne pojave su objasniti snaga. Promatranje fenomena indukcije pokazalo je da kada je krug bio zatvoren, igla se preselio se okomito na žice. S druge strane, isto je vrijedilo kada je krug bio zatvoren, ali je smjer električne struje bio obrnut. U ovom slučaju, smjer kretanja iglom se ukida. Dakle Oersted utvrdio da sila okomito na žice pojavio kao postojala električna struja prolazi kroz nju. Zašto magnetni pol od igle obično vrti oko thread? Što je zajedničko struje i magnetizam? Što nije jasno? Za obavljanje svoje eksperiment Faraday, žice omotan sa dvije strane mekom željezne jezgre. U nit je nazvao bateriju, a drugo, a galvanometar, što je uređaj koji se koristi za otkrivanje i mjerenje električne struje. Motivirani drugih pokusa je vodio studiju i drugih znanstvenika, među kojima ifrancuski-DRE-Marie Amper(1775-1836), Faraday vjeruje da je prolaz struje u žicu spojen na bateriju izazvati struje biti otkriven galvanometar. Tekst se u slijedu, preveli Dias (2004), predstavlja opis kako je Faraday izgradio svoju eksperimentalnu aparat. To je prsten od željeza (slatko) petlje sa 7/8 inča debljine i 6 cm u vanjskom promjeru. Nekoliko skreće bakrene žice su omotan oko prstena polovici, okreće se odvaja od pamuka i niza - postojala su tri žice duljine po oko 24 metara dug i oni mogli biti povezani kao produžetak ili samo koristiti kao zasebnih komada, izolirani jedni od drugih. Poziv na toj strani prstena A. S druge strane, već provedena u razmaku, bio rana žice na dva dijela zajedno, što čini oko 60 metara u duljinu, smjer se kao jedan od prvih zavoja, ova strana poziv B.(FARADAY. Citirano prema Dias, 2004, str. 44) Sljedeći dijagram predstavlja eksperimentalni aparat koristi Faraday. Suprotno onome što je očekivao, Faraday napomenuti da samo pojavio neki utjecaj na galvanometar (strana B) prilikom otvaranja ili zatvaranja prekidača (strana). Faraday obavlja druge eksperimente, ali rezultat je uvijek bio isti: samo pojavio neki utjecaj na B strani kada je struja na strani je pokrenuti ili zaustaviti, odnosno kada je spoj strana je zatvorena ili otvorena. Imajući krug zatvoreni krug, ništa nije primijetio na strani B.
