Thermoelectric Effect in Polarized Conductors

AI Thread Summary
The discussion centers on the Thermoelectric Effect, which involves the generation of voltage due to a temperature difference in a conductor with resistance. A user inquires whether placing a conductor in an electric field will create a temperature difference at its ends. Another participant clarifies that a conductor in an electric field is an equipotential body and does not develop a temperature difference solely from polarization. The distinction between potential difference causing current flow and the electrostatic situation is emphasized. Overall, the consensus is that polarization in an electric field does not lead to a temperature difference in the conductor.

Hi All,

I was just reading about the Thermoelectric Effect, and had a question:

In this phenomenon, when there is a temperature difference on each side of a conductor with a finite resistance, a voltage develops (due to diffusion of electrons). Similarly, when a voltage is applied across a conductor, a temperature difference develops.

My question is, if we place a conductor in an electric field, polarizing it, will a temperature difference develop between the ends of the conductor? From my understanding, a voltage will develop across a conductor when it is placed in a electric field.

Thanks

Er.. no. A conductor, under electrostatic situation, is an equipotential body when placed in an electric field. You should not confuse a potential difference applied to a conductor (with a non-zero resistance) resulting in current flow, with the situation above.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
