Curl of magnetic field derivation

WebThe magnetic field is NOT conservative in the presence of currents or time-varying electric fields. A conservative field should have a closed line integral (or curl) of zero. Maxwell's fourth equation (Ampere's law) can be written ∇ × B = μ 0 J + μ 0 ϵ 0 ∂ E ∂ t, so you can see this will equal zero only in certain cases. 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".
