Electric Field on cyilnder

  1. Mar 25, 2015 #1

    I would like to create an electric field inside a cylinder. Is there any EXPERIMENTAL way to impose 120V DC (or any higher or lower) voltage on the surface of a cylinder and generate electric field inside it?

    I'm specifically looking for "experimental" approaches.

    Thank you very much :)

    Look up "cylindrical capacitor" for an example.

    The question is actually too general to answer properly, i.e. you can put an electric field inside a cylinder the same way you put one anywhere else.
    You have not said what the cylinder is made of - you can always, for eg. , embed charges in a cylinder made of an insulating material.
    You have not specified the dimensions of the cylinder ... or if it is hollow or what.

    Don't know what you mean by "experimental approach" - is this different from just building one?

    What is this for?

    the material is stainless steel. the hollow cylinder (tube) already exist and we would like to impose electric field inside it.

    Dimensions? What sort of (geometry etc) field - can you describe what you are after?
    To give you an idea how wide open your question is: shine light into the cylinder and there is an electric field in it; put any electric circuit in it, same; put an atom in it... so you see it would help to narrow it down.
