What exactly is electric dipole moment & how it works/used? (don't go into deep mathematical calculations)
Please answer the question about the direction with good details. Don't just say that it's simply a convention because it's not. It surely has some deeper meanings attached to it.
I've seen a video on this recently. It said that permittivity of a medium is the resistance to build up an electric field inside that medium. The medium creates an opposing electric field when inside an external electric field reducing the neat External electric field (I knew these).
Then it said that this is very hard to work with these kind of fields that oppose each other like this. So, a trick was done & The scientists have defined polarization which is defined by vector 'P' and instead of going from positive to negative charge, Polarization goes from negative to positive charge. The opposite direction of what actually happens in the molecules. Then it said something about displacement vector (I don't understand much about this Vector)
So, my question -
Details about Electric Dipole Moment (significance) [I know the laws and Maths, you don't need to prove them, just tell me the significance of this & what it is anyway]
Is this polarization has something to do with the direction of The electric dipole moment? & if they are connected then please tell me the details about how & why they are connected? (but do not go into deep mathematical calculations)
My main question is Why the direction is like that? (details)
So, a good details about the whole electric dipole moment is what I need.
