i was also confused by this geographical-physical mismatch.

Yeah, i think it's not as trivial as it seems. thank you!

thank you for the very extended reply. you said in your final lines: "at the same potential" which is ... i suppose is non-zero with respect to ground. however the potential drop across the rod is 0 as electric field gradient from the Earth's field is canceled by the electric field established...

Thanks for answering! I am aware that such lines are just a way of representing a force field. what prompted me is that when i needed to think of how the magnetic field is directed between two bar magnets i should draw lines N -> S whereas by convention the direction is S-> N and this direction...

our planet is a big capacitor. there's a potential drop of about 130 V/m. therefore a conducting rod hanging perpendicular to the ground experiences a change of potential along its length. i am aware that a charge separation within a rod would take place with electrons collected near the higher...

It might seem trivial for most of you but i am confused by the definition of direction of magnetic lines. It's well known the magnetic field is directed from S to N but if one looks from outside and follows the magnetic line then one come from N to S. I am aware of that magnetic lines are closed...

Hello, I have puzzled myself with a question: what is the potential of a conducting rod in a homogeneous electric field (net rod charge = 0)? To be more exact I imagine a conducting rod suspended on a non-conducting thread in the Earth electric field near and perpendicular to its surface. If...
