Can a Scalar Field Exist Without a Net Source?

[Shubham135]

The magnetic field has no net source or sinks i.e. number of sources are equal to the number of sinks. Can a scalar field also have no net source? Or a source is required for a scalar field?

In this context a "source" is a non zero divergence. Do you have a definition for the divergence of a scalar function?

This is precisely my question
