Divergence

Divergence is a function that maps a vector field F on a scalar field, as

 


Explanation

Divergence gives the intensity at which a vector field will vary. For a flow it gives the divergence for each point and tells whether somethings flows to that point or flows from that point.

 


Example 1

The Maxwell equation of the electrical charge density is

where

    ∇⋅ Divergence
    D Electrical displacement
    ρ Electrical charge density
