    What exactly is flux?

    What IS magnetic flux? Is magnetic flux a physical sub atomic particle of sorts? Or is it simply a tool we use to quantity of the strength of a magnetic field?

    Magnetic flux, Φ, is the measure of the strength of a magnetic field.

    I don't know what it is, but I know it belongs in a capacitor.

    It's when you can't pay your buddy back the money you owe him.

    "Sorry, mate, I am in a bit of a flux, right now."
    Would you like a dream with that?

    Isn't flux the effect that the magnet has on the electrons of atoms that causes the distortion field around a magnet. aka if you do the iron filing trick. I've always been kind of curious as to what the "flux" actually is. E.g. if it is the effect that the magnet has on electrons of atoms then do magnets have a sphere of influence in outer space?

    No, not really. You're talking about the magnetic field, not the magnetic flux, though they are closely related. You can think of the magnetic flux as the quantity of magnetic field flowing through a defined area like the interior of a loop of wire. That description is not entirely accurate because the field doesn't really flow. Think of it this way: If you could draw lines in three dimensions showing the magnetic field, in which the lines are in the direction of the field at each point, then the density of the lines in a given region is proportional to the magnetic field density. Then you draw a loop and count the lines going through the loop, and that count is proportional the the magnetic flux through the loop. Same concept applies to gravitational flux and other types of fields.

    conductors and fluxes? Read this....



    [From The Institute of Electrical Engineers, Students Quarterly Journal 25]

    For a number of years now, work has has been proceeding in order to bring
    prefection to the crudely conceived idea of a machine that would work to not
    only supply inverse reactive current, for use in unilateral phase detectors, but
    would also be capable of automatically synchronising cardinal grammeters. Such
    a machine is the 'Turboencabulator'. Basically, the only new principle involved
    is that instead of the power being generated by the relaxive motion of
    conductors and fluxes, it is produced by the modial interactions of magneto-
    reluctance and capacitive directance.

    The original machine had a base-plate of prefabulated amulite, surrounded by a
    malleable logarithmic casing in such a way that the two spurving bearings were
    in direct line with the pentametric fan, the latter consisted simply of six
    hydrocoptic marzelvanes, so fitted to the ambifacient lunar vaneshaft that side
    fumbling was effectively prevented. The main winding was of the normal lotus-
    o-delta type placed in panendermic semiboloid solts in the stator, every seventh
    conductor being connected by a non-reversible termic pipe to the differential
    girdlespring on the 'up' end of the grammeter.

    Forty-one manestically placed grouting brushes were arrranged to feed into the
    rotor slip stream a mixture of high S-value phenyhydrobenzamine and 5 percent
    reminative tetraiodohexamine. Both these liquids have specific pericosities
    given by p=2.4 Cn where n is the diathecial evolute of retrograde temperature
    phase disposition and C is the Chomondeley's annual grillage coefficient.
    Initially, n was measured with the aid of a metapolar pilfrometer, but up to the
    present date nothing has been found to equal the transcetental hopper dadoscope.

    Electrical engineers will appreciate the difficulty of nubbing together a
    regurgitative purwell and a superaminative wennel-sprocket. Indeed, this proved
    to be a stumbling block to further development until, in 1943, it was found that
    the use of anhydrous nagling pins enabled a kyptonastic boiling shim to be
    tankered.

    The early attempts to construct a sufficiently robust spiral decommutator failed
    largely because of lack of appreciation of the large quasi-pietic stresses in
    the gremlin studs; the latter were specially designed to hold the roffit bars to
    the spamshaft. When, however, it was discovered that wending could be prevented
    by the simple addition of teeth to socket, almost perfect running was secured.

    The operating point is maintained as near as possible to the HF rem peak by
    constantly fromaging the bituminous spandrels. This is a distinct advance on
    the standard nivelsheave in that no drammock oil is required after the phase
    detractors have remissed.

    Undoubtedly, the turboencabulator has now reached a very high level of technical
    development. It has been successfully used for operating nofer trunnions. In
    addition, whenever a barescent skor motion is required, it may be employed in
    conjunction with a drawn reciprocating dingle arm to reduce sinusoidal
    depleneration.

    Flux is actually a mathematical term. It's integrating a vector field over a bounded surface.


    It might be easiest to understand flux if you think about water flow in a pipe. Assuming the velocity is the same all through the pipe, if you multiply the velocity of the flow (m/s) times the cross-sectional area of the pipe (m^2) you have the volumetric flux through a cross-section of the pipe (m^3/s). That's flow rate when you're talking about fluids in pipes, but you can measure flux of any vector field over any surface.

    A magnetic field can be represented as a vector field, which is what you see when you sprinkle iron filings around a magnet. The filings line up in the direction of the magnetic field vectors. You can define a surface anywhere you want around the magnet, and integrate the vector field over that surface, and that's the magnetic flux through that surface.

    Also, flux is the stuff that helps the metals stick to each other in soldering, welding, etc.

    The guy with a physics degree gives a thumbs up +1 to most of the statements above.

    Flux is just flow, or specifically a way of using a vector to describe the flow intensity and direction through a specific plane of area.

    Magnetic flux is just another way of describing a particularly interesting part of a particular magnetic field.

    So on the subject of magnetism anyone here read Jackson? (if you have you know which jackson I'm talking about...if not don't worry much, your life is significantly saner without reading the book)
