comment Are electric field lines due to Faradays law closed?
For completness: The $\nabla \times \cos(kz - \omega t)\hat x = -k\sin(kz - \omega t)\hat y \neq 0$

comment Experiments which show the phenomenon of closed electric field lines
Thanks for your try, but this is all general stuff which is pretty clear and does not really relate to my questions.

comment Are electric field lines due to Faradays law closed?
But the curl of the electric field in the wave is not zero? What is then the reason that introductory texts often say that the field lines are closed in induced electric fiels? Can one add some reasonable restrictions to make this claim true? If so, how to prove it?

Another point that's not clear is the role of the boundary conditions in this derivation.

comment Calculate electric field induced by a changing magnetic field
Regarding your analogy: The magnetic field in the case of the wire I would calculate via the Biot-Savart law. Is there an analogous way for this in the case of the induction?

comment Calculate electric field induced by a changing magnetic field
Thanks. Especially the part about $r\to \infty$ was helpful. However I don't fully understand the symmetry argument. Intuitively in the case of the current in the wire the current is along the $x_3$-axis, which gives you a distinguished axis. However this seems not to be the case in the case of Faradays law. So why not integrate around a circle (inside the magnetic field region) around a point other than the origin?

@ScroogeMcDuck How would you do this in detail?
