Electromagnetic Field Theory
What is the value of magnetic vector potential due to an infinitesimally small current element, evaluated at infinite distance from it?
An electric flux line is an imaginary path or a line drawn in such a way, that its direction at any point is the direction of electric field at that point.
For a uniform long charged line with l1 c/m the electric field intensity E is given as E = ρL/(π ε0.r).
Gauss’s law states that total electric flux through any surface is equal to the total charge enclosed by surface.
