    • Vortex

      In fluid dynamics, a vortex (plural vortices/vortexes)[1][2] is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved.[3][4] Vortices form in stirred fluids, and may be observed in smoke rings, whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone, tornado or dust devil.

      Vortices are a major component of turbulent flow. The distribution of velocity, vorticity (the curl of the flow velocity), as well as the concept of circulation are used to characterize vortices. In most vortices, the fluid flow velocity is greatest next to its axis and decreases in inverse proportion to the distance from the axis.

      In the absence of external forces, viscous friction within the fluid tends to organize the flow into a collection of irrotational vortices, possibly superimposed to larger-scale flows, including larger-scale vortices. Once formed, vortices can move, stretch, twist, and interact in complex ways. A moving vortex carries with it some angular and linear momentum, energy, and mass.

      • Fact

        Answers. This curl can in principle be any suitable vector field, though because it is a curl it is required to have zero divergence, i.e. ... If there are no currents, i.e. in vacuum, then yes, the magnetic field will have zero curl.

          It should be obvious that attempting to ascribe a vortex
          to a static magnetic field is fraught with problems.

          • You are missing the point here,

            A vortex inside a 3D medium volume (not surface) will produce a torus!! with zero divergence ∇ . B = 0 thus full curl:

              • No way.

                No way wil any vortex fit the bill, a vortex must involve a flow.
                Said flow will require energy input and as we all know there’s
                no energy output associated with a permanent magnet.
                Altogether a fail!!!

                • Read this

                  During factory acceptance tests (FATs) carried out with the customer present, we recorded a result of 99.05% full load efficiency on a 44 megawatt, 6-pole, synchronous motor. The motor was included in a contract for six motors of the same design and they all had test results above 99% efficiency. The contract had guaranteed an efficiency of 98.80%.

                  Now tell me humans haven't got a fair idea about magnetism.

                    Something I've been telling Ufopolitics for like 3 years on, since he started pushing Ken's theories on us. There is no flow in a static magnetic field, like that of a permanent magnet.

                      So, how the force of lines are formed in the first place then if there was no flow to begin with?

                      Can you draw a line without moving the pencil?

                      There is no force in nature without motion involved.

                      • No lines

                        But there aren't any lines involved.
                        The field is everywhere.
                        Magnetism is just a perturbation of said field.
                        Gravity and Magnetism are just forces, if they caused motion
                        we would have perpetual motion machines.
                        When one feels the force it's your hand that's instigating the motion.
                        With a Ferrocell the lines are deceiving, if you were to have a
                        bigger light source you would observe that a whole sheet of
                        the cell becomes illuminated.This becomes obvious if you carefully
                        study the Bic lighter example.
                        You can't lightly dismiss current research into particles, there's
                        a lot that's been predicted many years ago that's now been validated.
                        Quanta seems to be fundamental and it's very exciting, it's just the
                        beginning!!!!

                          Using your language, the pencil is the magnetizer at the magnet factory. Once the line is drawn, the pencil is no longer needed.

                            • Virtual photon

                              They are not, and should not be thought off as, real particles. ... They exchange energy and momentum through the quantum fields and this can be modelled by a sum of various particles. So you cannot detect a virtual photon with your photon detector and measure its frequency because the virtual photon isn't really a photon.
