Mechanism of charge interaction?

  1. Oct 31, 2008 #1
    One of the core concepts in electric field theory is that charges exert a force on one another: a positive charge "pushes out," and a negative charges "pulls in."

    What is the mechanism by which charges interact with one another? How does one charge "feel" the presence of another?

    Hi Sharky! :smile:

    I think the official view is that charges only feel the field, and its gradient … they don't know what's causing the field.
