"WebThe symbol for divergence is the upside down triangle for gradient (called del) with a dot [ ⋅ ]. The gradient gives us the partial derivatives ( ∂ ∂ x, ∂ ∂ y, ∂ ∂ z), and the dot product with our vector ( F x, F y, F z) gives the divergence formula above. Divergence is a single number, like density. Divergence and flux are ... " - Divergence of magnetic flux density

The best visual picture I have of this is a fluid flow. Imagine water spewing out of a tap - this has positive divergence; the tap is a source of the flow (density times velocity) of the water. Conversely you could imagine water dropping down a plug ...

WebJul 23, 2009 · The divergence measures the flow of a field out of a region of space. The del operator takes the gradient of the field, which measures the tendency of the field to diverge away in space (or the opposite). So when we take the divergence of the electric flux density, we are measuring how quickly the tendency of the flux to diverge in a given … WebSep 12, 2024 · The integral of a vector field over a surface is a scalar quantity known as flux.
