Electric field of water dipole

AI Thread Summary
A single water molecule generates a permanent electric dipole that creates an intrinsic electric field, with the direction of the field being along the line connecting the two charges. When another water molecule is nearby, it will respond to the dipole electric field of the first molecule by becoming polarized. The interaction primarily involves the permanent dipoles of both molecules, while induced dipoles are considered a secondary effect. The electric field vector is tangent to the field lines surrounding the dipole, which are not limited to the dipole axis. Understanding these interactions is crucial for grasping the behavior of water molecules in various contexts.

I cannot find the answer to my question anywhere on the internet so hopefully someone here will end my long search with the correct answer.
It is well known that a single water molecule has a permanent electric dipole which produces a dipole intrinsic electric field. Let's say the dipole is pointing in the x direction.. my question is: what is the direction of this electric field? If there is another water molecule nearby, how will it respond to the dipole electric field of the first molecule? (without taking account of hydrogen bonding, external fields, or any other issues.. it is just a question about the electric field generated by a single water molecule and how it polarizes another molecule).

The first link shows the direction of E along the line connecting the two charges only. E lines have a certain distribution around the dipole

but I cannot figure out from that how the second molecule will respond to the first one (as I explained in the question). The second link you posted talks about interaction between dipoles.. what I need to know is in which direction a single water dipole polarizes another molecule (being water or not).
 
Both water molecules are dipoles. So the dominant term in the interaction will be the one between the permanent dipoles. The induced dipoles will be a higher order correction.
The figures show the field lines around the dipole. Not just along the axis. These curves are the field lines. The electric field vector is tangent to these field lines, at any point.
 
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...
