Research Faraday did that the most important
experimental scientist of his day were the fields of electricity and
magnetism. After
the discovery of electromagnetism Oestered of 1819, Faraday reproduced
the experiment in 1821 and deepened his studies in this field, after
ten years of work discovered electromagnetic induction.
Faraday came to his discovery wrapping around a ring of iron two
separate coils. Connected
the heads of a coil (circuit induced) galvanometer, and the heads of
the (circuit inducer) an electric battery; closing circuit of the
needle stack of galvanometer moved in one direction
and opening the circuit was moving in the direction reverse.
Subsequently Later Faraday discovered that introducing or removing a
magnet from a conductor wound to blows, related to a product
galvanometer was a movement of the index, was produced in practice a
small electric current was able to obtain an electric current from a
magnet , to induce electricity using a magnet. she understood
immediately that the production of induced currents in a circuit was
not sufficient presence of the magnet, but needed his movement,
variation of the magnetic field induced. |
