Magnetic flux Definition: a measure of the strength of a magnetic field over a Symbol: φ. Collins English Dictionary. Copyright © HarperCollins Publishers. Precise Measurement, Easy use, Multi-Channel, Visit Offical Site! Enter which letters you already have. Given a flux according to the electromagnetism definition, the corresponding flux densityif that term is used, refers to its derivative along the surface that was integrated. It gives the measurement of the total magnetic field that passes through a given Dixie Press Online area. These fluxes are vectors at each point in space, and have a definite magnitude and direction. As before, the surface is assumed to be Worms Armageddon Online Spielen, and the flow is assumed to be everywhere perpendicular to it. Main article: Faraday's law of induction. Österreichisch Romme This law is a consequence of the empirical observation that magnetic monopoles have never been found. Flux describes any Bet365 Kostenlos that appears to pass or travel whether it actually moves or not Dolphins Pearls 2 Online a surface or substance.

We'll assume you're ok with this, but you can opt-out if you wish. This is sometimes referred to as the probability current or current density,  or probability flux density.
As a mathematical concept, flux is represented by the surface integral of a vector field , . For the second, n is the outward pointed unit normal vector to the surface.
The surface has to be orientable , i. Also, the surface has to be actually oriented, i. The surface normal is usually directed by the right-hand rule.
Conversely, one can consider the flux the more fundamental quantity and call the vector field the flux density. Often a vector field is drawn by curves field lines following the "flow"; the magnitude of the vector field is then the line density, and the flux through a surface is the number of lines.
Lines originate from areas of positive divergence sources and end at areas of negative divergence sinks. See also the image at right: the number of red arrows passing through a unit area is the flux density, the curve encircling the red arrows denotes the boundary of the surface, and the orientation of the arrows with respect to the surface denotes the sign of the inner product of the vector field with the surface normals.
If the surface encloses a 3D region, usually the surface is oriented such that the influx is counted positive; the opposite is the outflux.
The divergence theorem states that the net outflux through a closed surface, in other words the net outflux from a 3D region, is found by adding the local net outflow from each point in the region which is expressed by the divergence.
If the surface is not closed, it has an oriented curve as boundary. Stokes' theorem states that the flux of the curl of a vector field is the line integral of the vector field over this boundary.
This path integral is also called circulation , especially in fluid dynamics. Thus the curl is the circulation density.
We can apply the flux and these theorems to many disciplines in which we see currents, forces, etc. One way to better understand the concept of flux in electromagnetism is by comparing it to a butterfly net.
The amount of air moving through the net at any given instant in time is the flux. If the wind speed is high, then the flux through the net is large.
If the net is made bigger, then the flux is larger even though the wind speed is the same. For the most air to move through the net, the opening of the net must be facing the direction the wind is blowing.
If the net is parallel to the wind, then no wind will be moving through the net. The simplest way to think of flux is "how much air goes through the net", where the air is a velocity field and the net is the boundary of an imaginary surface.
An electric "charge," such as a single electron in space, has a magnitude defined in coulombs. Such a charge has an electric field surrounding it.
In pictorial form, an electric field is shown as a dot radiating "lines of flux" called Gauss lines. Two forms of electric flux are used, one for the E -field:  .
This quantity arises in Gauss's law — which states that the flux of the electric field E out of a closed surface is proportional to the electric charge Q A enclosed in the surface independent of how that charge is distributed , the integral form is:.
If one considers the flux of the electric field vector, E , for a tube near a point charge in the field of the charge but not containing it with sides formed by lines tangent to the field, the flux for the sides is zero and there is an equal and opposite flux at both ends of the tube.
This is a consequence of Gauss's Law applied to an inverse square field. The flux for any cross-sectional surface of the tube will be the same.
Here the expression "flux of" indicates a mathematical operation and, as can be seen, the result is not necessarily a "flow", since nothing actually flows along electric field lines.
The quantity arises in Faraday's law of induction , where the magnetic flux is time-dependent either because the boundary is time-dependent or magnetic field is time-dependent.
In integral form:. The time-rate of change of the magnetic flux through a loop of wire is minus the electromotive force created in that wire.
The direction is such that if current is allowed to pass through the wire, the electromotive force will cause a current which "opposes" the change in magnetic field by itself producing a magnetic field opposite to the change.
This is the basis for inductors and many electric generators. Using this definition, the flux of the Poynting vector S over a specified surface is the rate at which electromagnetic energy flows through that surface, defined like before: .
The flux of the Poynting vector through a surface is the electromagnetic power , or energy per unit time , passing through that surface.
This is commonly used in analysis of electromagnetic radiation , but has application to other electromagnetic systems as well.
Confusingly, the Poynting vector is sometimes called the power flux , which is an example of the first usage of flux, above. From Wikipedia, the free encyclopedia.
