How to create a "projected" electric field
First of all, apologies for my naivete, it's been many years since I've studied electromagnetism or electrical engineering in detail, but here goes anyway...
I am trying to generate a small electric field (about the size of a marble). I am aware of the method of using two oppositely charged plates to create a field between them, but what I'm looking for is something more like a "projected" electric field around a point - or in other words, one that extends outward rather than inward.
My goal is to create a small electric field that can be detected by a capacitive touchscreen (projected capacitive in this case) from a small distance - for example from about 1 cm.
I don't know if this is even technically feasible or that I'm approaching it in the right way.. I am open to any and all suggestions.
Thank you!
