Revolving flux refers to the magnetic flux that changes direction and magnitude over time, typically in the context of alternating current (AC) systems or rotating machinery. It is generated by rotating magnetic fields, such as those produced in synchronous motors or generators. This changing flux induces electromotive force (EMF) in conductors, enabling energy conversion and transmission in various electrical devices. Understanding revolving flux is crucial for designing efficient electrical systems and machines.

Difference between flux linkage and flux leakage?
i) leakage flux is those flux which goes through the air and linkage flux is those flux whose go through the cell. ii)leakage flux is the loss at flux but linkage flu is warning flux. iii)leakage flux is cause of eddy current loss and linkage flux is case of copper loss.

Air gap flux is termed as useful flux why?
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!
Is flux only produce in ac supply or in both ac and dc?
Flux is produced in both AC and DC systems, but the nature of the flux differs. In DC circuits, the magnetic flux is constant, as the current flows in one direction. In AC circuits, the magnetic flux changes direction and magnitude periodically, resulting in a time-varying magnetic field. Thus, while both types of current can produce flux, AC generates a dynamic flux due to its oscillating nature.
Is there any device which can convert constant magnetic flux into variable flux?
A generator, in general.

What is leakage factor?
The Ratio of the total flux ( flux in iron path) to the useful flux (flux in air gap)
Difference between mutual flux and leakage flux?
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. flux produced by one coil ,but linked with another coil then the flu is said to be mutual flux.

What are the two main types of flux?
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.
How flux is related to speed?
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.
In transformer core flux depends on voltage whereas leakage flux depends on current?
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.
