Curl of magnetic field derivation
WebThe Scalar Magnetic Potential. The vector potential A describes magnetic fields that possess curl wherever there is a current density J (r). In the space free of current, and thus H ought to be derivable there from the gradient of a potential. Because we further have The potential obeys Laplace's equation. Example 8.3.1. WebTake your hand extend your thumb and curl your fingers. If the thumb is the model for the flow of the vector field, then $$\nabla \times \vec v =0.$$ If the curling of your fingers is the model for the flow of the vector field then $$\nabla \times \vec v \neq 0$$ and the measures the rotational motion of the vector field. Hence the name "curl".
