There are certain properties of lines of force, I know they are not real, but following these 'properties', given position and intensity of magnetic/electric field sources we will be able to reconstruct these lines without any practicals.
So I have a problem with lines of forces.
Sources say -
Assuming 2 sets of lines for forces emerging from any 2 plate sources (so as to make the lines parallel to each other), the lines which are parallel (i.e having the same direction of propagation) will repel each other, and those which propagate in the opposite direction will try and merge with each other.
Diagrammatically, lines parallel to each other -
------------------->
------------------->
------------------->
------------------->
Will repel, and those having different direction of propagation -
-------------------> <-------------------
-------------------> <-------------------
-------------------> <-------------------
-------------------> <-------------------
Will attract and try to merge with each other.
I do not find this true.
Suppose, in this case, suppose both the plates are positively charged -
|---> <---|
|---> <---|
|---> <---|
|---> <---|
Although the direction of propagation of these lines are against each other, they will repel, similarly, putting a negatively charged in front a positively charged one -
|---> --->|
|---> --->|
|---> --->|
|---> --->|
Though these lines are parallel, they will try and merge with each other.
This is against what all the sources say.
So I say -
Electrical lines of forces will repel each other if its origin is from the same polarity of charge, else they'll attract...which appears to be working fine...
