Because in the leading load or capacitive load the armature reaction is magnetizing.Here the stator flux adds up rotor flux and so the net flux of alternator increases and the net flux produces alternator's voltage.Hence the alternator's voltage rises.

Flux is related to the speed of change in a physical quantity through the concept of flux density. Flux density is the amount of flux passing through a unit area per unit time. The faster the change in the physical quantity, the higher the flux density.

Here is A Simple answer for this question
as you know that emf is induced in the conductor when there is change of flux linkage to the conductor which gives rise to the inducement of electric field in the conductor that provide drift velocity to the electrons hence emf is induced in the conductor but the last only till the change in flux in progress and becomes zero as soon as the flux linkages becomes constant hence we summaraize that for inducement of current there must be change in change of flux hence change in electric field that gives rise to allternating emf.

In mass transfer, flux is the amount of mass flowing through a unit area per unit time. Flux is represented by the symbol "J" and can be either molar flux (J) or mass flux (N). Molar flux (J) is the amount of moles of a component flowing through a unit area per unit time, while mass flux (N) is the amount of mass of a component flowing through a unit area per unit time. The key difference between the two is that molar flux is expressed in moles per unit area per unit time, while mass flux is expressed in kilograms per unit area per unit time.

when a current flow through the coil then flux produced around the coil . if the flux linked same produced coil only then the flux is said to be leakage flux.

The rise time of a system is approximately equal to 2.2 times the time constant. A smaller time constant will result in a faster rise time, while a larger time constant will result in a slower rise time.

when alternating current flows in the field winding, an alternating flux is produced in the field core.A portion of this flux links with the shading coil,which behaves as a short circuit secondary of a transformer.A voltage is induced in the shading coil, and this voltage circulates a current in it.The induced current produces a flux called the induced flux which opposes the main core flux.The shading coil thus causes a flux in the shaded portion to lag behind the flux in unshaded portion of the pole.At the same time the main flux and shaded pole flux displaced in space.This space displacement is less than 90 degree.Since there is time and space displacement between two fluxes,the conditions for setting up a rotating magnetic field is produced.Under the action of the rotating flux a starting torque is developed on the cage rotor.The direction of this flux is from unshaded to shaded portion of the pole.and the rotor moves in clockwise direction

It is not recommended to use expired liquid flux for soldering as the effectiveness of the flux diminishes over time, which can lead to poor soldering results. It is best to use fresh flux to ensure proper soldering and avoid issues such as weak joints or oxidation. Expired flux may also contain harmful chemicals that could pose health risks during soldering.

In the first movie the car ran on gasoline and the time circuits and flux capacitor ran on plutonium (but they had to use a lightning bolt at one stage).
In the second movie the car ran on gasoline and the time circuits and flux capacitor ran on rubbish (that the new Mr Fusion attatchment turned into power).
In the third movie the car ran on gasoline (but they were in 1885 so they had to use a train to push it instead) and the time circuits and flux capacitor ran on rubbish still.

Types of flux - Electric and Magnetic Flux.
Electric field flux through a closed surface is equal to the change enclosed in the surface, or the rate of change of magnetic flux is equal to the induced voltage around the surface.

The ratio of reflected flux to incident flux.
Flux - The time rate of flow. For example, volume per hour is the flux of a fluid.
Reflectance also is called Light reflection Value. In lighting design, we need to consider all reflectance for proper lighting simulation to real time environment. In general, wall, floor, ceiling reflectance will be 50%,80%, 20-40%. It also depends on painting color of room

In a Transformer, Core flux is the difference of primary flux and Secondary flux which are opposite to each other in direction. There difference is equal to the no load flux at all loads.
So, some of primary flux passes through the core and remaining becomes leakage flux (Because Secondary flux forces it to get out of the core). Same is the case with Secondary flux.
Now, flux is directly proportional to Voltage and Current.
When Current increases due to increased load (and voltage remains same):
Then both primary and secondary flux increase. Because both of them increase, so there difference remains same. And all remaining flux is forced out. Hence leakage flux increases with current, but Core flux remains constant.
When Primary Voltage is increased:
Then only primary flux increases. So difference of this new increased primary flux and previous same secondary flux increases. Hence Core flux increases with voltage, But leakage flux does not.
That's how In transformer core flux depends on voltage whereas leakage flux depends on current.

dc flux is caused by dc current (flux and current are proportional), it is a constant value. Put an inductor (or transformer winding) across a battery and you will get dc flux.
ac flux is caused by ac current (flux and current are proportional), it is a moving value, the flux moves with the current, typically cyclical but the waveform is arbitrary as long as we're moving.

Basically useful fluke is the flux that flows with in the magnetic circuit of an armature. That is why when there is an air gap the flux enters the armature which makes it useful flux! Hope that answers your question!

once flux density is known multiply to it the area perpendicular to the flux lines . the product is the total flux passing through the area. If field strength is known , get the flux density by pultiplying to it the permeability of the medium. then flux can be obtained as above. from : govind Kunkolienker kunkolienker@yahoo.com

The rate of change of flux equals the induced electromotive force or voltage in a circuit, as described by Faraday's law of electromagnetic induction. Mathematically, this relationship is expressed as: (\text{EMF} = -\frac{d\Phi}{dt}), where EMF is the induced voltage, (\Phi) is the magnetic flux, and (\frac{d\Phi}{dt}) is the rate of change of magnetic flux over time.
