| Keywords: Faraday emf experiment.svg Inkscape In his attempt to produce an electric current from a magnetic field Faraday used an apparatus like that shown in Fig 21 “1 A coil of wire X was connected to a battery The current that flowed through X produced a magnetic field that was intensified by the iron core Faraday hoped that by using a strong enough battery a steady current in X would produce a great enough magnetic field to produce a current in a second coil Y This second circuit Y contained a galvanometer to detect any current but contained no battery He met no success with steady currents But the long-sought effect was finally observed when Faraday saw the galvanometer in circuit Y deflect strongly at the moment he closed the switch in circuit X And the galvanometer deflected strongly in the opposite direction when he opened the switch Faraday concluded that although a steady magnetic field produces no current a changing one can Such a current is called an induced current For more information see Faraday's law of induction and electromagnetic induction 2011-09-20 own Eviatar Bach cc-zero Uploaded with UploadWizard Induction Galvanometers Files by User InverseHypercube ImageNote 1 775 52 259 202 1035 365 2 Galvanometer ImageNoteEnd 1 ImageNote 2 334 116 261 247 1035 365 2 Iron ring ImageNoteEnd 2 ImageNote 3 43 72 125 251 1035 365 2 Battery ImageNoteEnd 3 | ||||
