I would like to know if a small electric current can be created in a closed loop of wire by using a strong electric field to move the free electrons within the closed loop of wire.
To create this strong electric field, a high voltage DC power supply could be used, one that say generates 100 kV. The power supply's two electrodes will need to be covered with insulation, such as mica, so no electric current can flow between them, yet the mica will allow the electrodes' electric charges to pass through them.
I believe that in order for the free electrons on the outer surface of the wire to be moved, the section of wire between the two electrodes cannot have any wire insulation around it. Also, the wire's insulation will need to be a material with a very high dielectric constant. I think an ideal material to use could be calcium copper titanate, which has a dielectric constant/relative permittivity of >250,000 (per Wikipedia). I am not sure if this material can completely block an electric charge of 100 kV for I have never worked with this material before.
To illustrate how this would work, I have created the following drawing. (This drawing is showing a cross-sectional view and the two electrodes have holes in the middle of them with the wire passing through them.)
I believe that the free electrons on the outer surface of the wire will be moved towards the positive electrode and they will want to stay close to it, but they will be pushed pass this electrode due to the continuous flow of other free electrons being sent forward by the repulsion force coming from the negative electrode. The result should be that there should be a flow of free electrons moving in the closed loop of wire which should create a small electric current.
Can an electric current be created within a closed loop of wire using an electric field?
