Discussion Overview
The discussion revolves around the behavior of ions when they collide with oppositely charged electrodes, specifically regarding the presence and nature of the Lorentz force during these interactions. Participants explore both general concepts and specific scenarios, including the implications of ion behavior in an imperfect vacuum and the context of coating processes.
Discussion Character
- Exploratory
- Technical explanation
- Conceptual clarification
- Debate/contested
Main Points Raised
- Some participants question whether ions experience a Lorentz force when colliding with oppositely charged electrodes, particularly when gaining or losing electrons.
- One participant highlights the need for clarity on whether the inquiry is about general ion behavior or a specific case involving negative ions hitting positive electrodes.
- Another participant mentions that in coating applications, ions are attracted to charged surfaces and may not continue moving after collision.
- In the context of an imperfect vacuum, participants discuss whether ionized gas molecules would experience a Lorentz force, suggesting that the presence of charge and a net electric field would result in such a force.
- There is a suggestion that the complexity of the situation may lead to different interpretations of the Lorentz force's effects.
Areas of Agreement / Disagreement
Participants express differing views on the specifics of the Lorentz force's role in ion interactions with electrodes. There is no consensus on the general behavior of ions in these scenarios, and the discussion remains unresolved regarding the implications of the Lorentz force in various contexts.
Contextual Notes
Participants note the importance of defining the specific conditions under which the Lorentz force is considered, including the nature of the ions, the type of electrodes, and the surrounding environment (e.g., imperfect vacuum). There are also unresolved questions about the assumptions made in the discussion.
Who May Find This Useful
This discussion may be of interest to those studying plasma physics, ion behavior in electric fields, and applications involving ionized gases and surface coatings.

You are making several leaps of assumptions here that appears to turn this into something rather specific.
First of all, what exactly are you trying to learn here? Is it simply a general concept of what happens, in general, when ions hit the respective electrodes? Or do you specifically want, as depicted in your figure, the special case where a negative ion hit a positive electrode, and then this ion doesn't form anything else but moves (?) on? (see your figure).
Note that this type of phenomenon is often used in coating stuff. The ions are attracted to the charged surface, and they then bind to that surface, forming a thin coat, i.e. they don't move on. So it is hard to know if you just want to understand this in general, or of something more specific.

In an imperfect vacuum, where current is carried by ionized gas molecules, will the gas molecules experience such a lorrentz force?

As long as there is a charge, and there is a net electric field, there will always be a Lorentz force. Whether that force and produce what you and I want, or be described very simply, that's a different question.

Thank you. If you were searching for information for such a specific case, what would you google?
