Electric Field Lines: Can Charges Move on Conductors?

AI Thread Summary
Electric field lines are always perpendicular to the surface of a conductor, indicating that charges remain at rest on the surface without work being done. When an external electric field is applied at an angle to the conductor's surface, it can cause charges to move along the surface. This movement occurs due to the influence of the electric field generated by the charges on the conductor itself. Additionally, altering the charge density by redistributing charges can create a new electric field across the conductor. Understanding these principles is crucial for comprehending how charges behave in electric fields.

sir, we know that the electric field lines are perpendicular to the surface of the conductor ,it means charges are rest on the surface of the conductor ,there is no work done.
if we create an electric field such that the electric field lines are at a different angle to the surface of the conductor then charges are automatically move on the surface.
i want to know that it id possible or not? sir, please give me a sufficient answer about this topic.
thank you.

If that's not what you mean, then perhaps you mean the field generated by the charges on the conductor. What happens if you change the density? So I move, say, the negative charges to one end? What is across the conductor if that's the case? What does that generate?
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
