Ions & Lorentz Force: Collisions w/ Oppositely Charged Electrodes

[Samson4]

When ions collide with oppositely charged electrodes, do they experience a Lorentz force as they gain or lose electrons? Is there a force, ignoring the repulsion of the positive electrode, in the direction of the blue arrow depicted here?

Only information I find is on ionic fluids.

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?
