What is the interaction between two charged particles called?

There are a number of laws and principles which govern the different interactions between the number of charged particles. While, the charge particles posses the specific orientation of net positive or negative charge on its surface which provides the required information about the same particles if it interacts with any other charged particle in its space or region of influence in which they can effect any number of test charges.

But, there is a specific law which explains the properties of a charge particle when it interacts with some other particle in a given space or region, which is termed as, "the Coulombs law".
