RESPECTED SIR,
MANY PEOPLE SAY ELECTRIC FLUX HAS GOT NO PHYSICAL MEANING. I WOULD WANT TO KNOW WHAT EXACTLY IS ELECTRIC FLUX AND WHY IT HAS GOT NO PHYSICAL MEANING?
When a physical phenomenon cannot be "seen", it becomes more difficult to understand it. Two opposite charges attract each other can be verified by the movement or stickiness of charges but why do they do so, i.e. what is pulling them cannot be seen.
To visualise what is pulling them, the concept of lines is introduced. It is imagined that the place surrounding a charge is immersed with these lines and another charge kept there experiences force.
