Is electric field always 0 if potential at a point is 0?

AI Thread Summary
The discussion centers on the relationship between electric field and electric potential. While a zero electric field indicates a constant potential, a zero potential does not necessarily mean the electric field is zero. The potential is relative and typically referenced to infinity, making it crucial to consider potential difference rather than absolute values. The argument highlights that knowing the potential is zero does not provide definitive information about the electric field. Therefore, the conclusion is that potential being zero does not imply the electric field is also zero.

I understand that if electric field at any point is 0, it implies that potential is constant not necessarily 0. But what if the potential at a point is 0? Does it imply that electric field is 0? Me and my friend had an argument and I am in the favour of electric field not being 0. Do I win guys? Plz tell me I do

If the lectric field is zero at a point, then we know the gradient of the potential is null at that point.
If the potential is zero at a point, and this is the only information we have, we know nothing about the electric field

Potential is always relative to some other point. It's conventionally taken as referenced to 'Infinity'. It may be best to talk in terms of Potential Difference in this question.

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...
