Abstract

This paper making an experimental exploration of Foucault s currents (eddy currents) through a rotor magnetically coupled to computer hard disc (HD) that is no longer being used. The set-up allows to illustrate in a stimulating way electromagnetism classes in High Schools for mean of the qualitative observations of the currents which are created as consequence of the movement of an electric conductor in a region where a magnetic field exists.
