Curl of magnetic field derivation
WebWe can find the magnetic field that is caused by moving charges using a second right-hand rule. The magnetic field made by a current in a straight wire curls around the wire in a ring. You can find it by pointing your right thumb in the direction of the current in the wire and curling your fingers. 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".
Curl of magnetic field derivation

WebIn classical electromagnetism, magnetic vector potential (often called A) is the vector quantity defined so that its curl is equal to the magnetic field: =. Together with the electric … 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.

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.
