Examples of Poisson's Differential Equation for Rotational and Solenoidal Field
Magnetic Field in Conductor carrying Steady Current
Consider a conductor of electricity $C$.
Let $C$ be carrying a steady current $I$.
From Curl Operator: Magnetic Field of Conductor, the curl of the magneto-motive force per unit area $\mathbf H$ is given by:
- $\curl \mathbf H = \mathbf J$
Hence this satisfies Poisson's Differential Equation for Rotational and Solenoidal Field:
- $\curl \mathbf J = -\nabla^2 \mathbf J$
Rotational Motion of Incompressible Fluid
Let $B$ be a body of incompressible fluid.
Let $B$ be undergoing rotational motion.
Let $\mathbf V$ be the vector field which describes the rotational motion of $B$.
Then $\mathbf V$ satisfies Poisson's Differential Equation for Rotational and Solenoidal Field.
