Estudo e aplicação das correntes de Foucault

Abstract

This work will study the eddy current, which are induced currents. Will begin with a theoretical study of electromagnetic induction proposed by Michael Faraday, where he will explain that a variation in magnetic flux will induce an electric current in the conductor. Then will be studied by the method of inductance, where it will be seen that if the current in the vicinity of one of the ends of the solenoid suffer a variation, the magnetic field generated by the coils near the area where there was the current variation, will produce a magnetic flux variable on the other coils that form the solenoid, i.e. the circuit will produce a magnetic flux variable about himself, and he will induce a self-induced. After these theoretical studies will be seen the effects that the eddy current will produce in the conductors, for example, the magnetic damping that the conductors suffer due to the magnetic field and another example would be the electric generators that are devices with finality to transform the mechanical energy into electrical energy.
