Scalar Field:

A scalar field is similar to a vector field, but it assigns only a scalar value (magnitude) to each point in space, without specifying any direction.

Gradient: The gradient of a scalar field measures how rapidly the scalar quantity changes from one point to another.

Flux: Flux is the flow rate of a vector field through an imaginary surface. It represents how much of the vector quantity passes through the surface per unit area.
