Eddy Currents and Non Ferrous Metals.

We can call eddy currents that if you like,  but please note,  it  is not currents that the lines on your diagram represent.

The lines in the diagram are magnetic fields, quite a different thing, and at right angles to the current.

Both the driving currents, and any induced Foucault  currents associate with those lines of magnetic field are entirely out of the plane of the screen.

* (magnetic field lines tell you the pointing direction of an imaginary small compass, lines of current are about moving electric charges . This was not fully fixed in 1898 you may do marginally better with Electricity and Magnetism by Bleaney and Bleaney 1957 vol 1. however it is not a light read.).
