Charged Ion Beam and Electromagnetic Induction: A Neutralization Method

[Crazymechanic]

A rather simple question.
A confinement of positively charged ions , a tube from the confinement and in the end of the tube a metal plate at a negative potential , if the charged ions are let to run towards the negative metal plate (which they would normally do) the plate would loose it's negative charge.
Does a winding around the tube which is the path which the ions would take towards the negative plate would neutralise their charge due to electromagnetic induction in the windings which they would pass towards the plate?

No. The positive charged ions are atoms from which someone or something has stolen some of their electrons, and the only way of turning them back into neutral atoms is to return the missing electrons. The negative plate can do this by donating electrons to ions; the battery or whatever is maintaining it at a negative potential is providing a supply of electrons. The coil around the tube can't do that; back-EMF from the induction may slow the ions but it can't reduce their charge.

Well yes I understand that you can't just erase the ion charge as a property of atoms but I was rather thinking before the ions entered the tube with a winding around it they were say confined with a positive electrostatic confinement , now this positive confinement has raised their potential if I could say , and I was thinking that them passing through a coil would lower that as they would give the energy they had while coming out of the confinement to the coil through electromagnetic induction and so their energy would be atleast partly or fully converted to electrical current?

No.

Yes, although that's a completely different question than you originally asked. You're just turning fast-moving charged particles into slow-moving charged particles or vice versa.

Here we are again, CM. You are mixing the relationships between Charge, Field and Potential here, as before. If you bunch up ions, you do Work and increase the Potential in the beam. Total Energy is conserved so there must be a reduction in KE of the beam if PE is increased. The charge is not altered (charge density increases, locally) but the field on the periphery will increase in amplitude.
