1) Having in mind the Faraday-Lenz law, i'm still not sure if anything happens to it? [1) SOLVED] The area is always the same, the flux idem, flux density as well, so at first glance it would appear nothing happens? This problem was on a exam. 2) Let's say i have a permanent magnet and a wire like in the picture, should there be an emf, in the wires if we move them into or out of the magnetic field of the magnet? Being a wire, it can only produce flux lines (2-D) and they can't oppose the change in magnetic field. The one on the right because it only produces flux perpendicular to the magnetic field of the magnet, the one on the right, because it's a circle, and if one side of the circle counteracts the change of magnetic flux the other helps it. So basically i think this can be resumed in: can a straight line of wire have an emf on its ends generated by the change of the flux its subject to? Please do correct any errors in my thinking.
