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 there any device which can convert constant magnetic flux into variable flux?
A generator, in general.
How do you determine the flux constant of a PMSM?
Flux linkage is determined by magnets. The constant flux (Wb) per pole pairs induced in the stator windings of the magnets. Flux established by the permanent magnets produce three trapezoidal back EMP waveforms.
Can you do Welding Operation without flux?
Yes .... but most welds will not be as good as those using flux. SMAW with bare electrodes produces poor results. GTAW and GMAW are done without flux when an inert gas is used to protect the puddle. Some Oxy-fuel welding can be done with out it. In most applications flux is used not only to protect the molten puddle but also add ingredients to the weld.
What are Three functions of the electrode covering in manual metal arc mma welding?
3 FEATURES OF FLUX CORED ELECTRODES Flux cored electrodes combine the advantages of several of the welding processes we have discussed earlier. As with coated electrodes, the flux improves the weld metal chemi- cal composition and mechanical properties. As in gas metal arc welding and submerged arc welding, productivity is increased because the electrode is continuous. 7.3.0.1 Flux cored electrodes may be used for welding carbon steels, low alloy high strength steels, and the high strength quenched and tempered steels. They are also used for welding stainless steels and abrasion resistant steels. These will be covered in subse- quent lessons. 7.3.1 Functions of the Flux Ingredients - As with coated ingredients, each manufac- turer has his own formulas for the flux ingredients. The composition of the flux core can be varied to provide electrodes for specific applications. 7.3.1.1 The basic functions of the flux ingredients are: a) Deoxidizers and Denitrifiers - Since nitrogen and oxygen can cause porosity or brittleness, deoxidizers such as manganese and silicon are added. In the case of self-shielded electrodes, denitrifiers such as aluminum are added. Both help to purify the weld metal. b) Slag Formers - Slag formers such as oxides of calcium, potassium, silicon or so- dium are added to protect the molten weld puddle from the atmosphere. The slag aids in improving the weld bead shape and "fast freezing" slags help hold the weld puddle for out-of-position welding. The slag also retards the cooling rate, especially important when welding the low alloy steels. c) Arc Stabilizers - Elements, such as potassium and sodium, help produce a smooth arc and reduce spatter. d) Alloying Elements - Alloying elements, such as molybdenum, chromium, carbon, manganese, nickel, and vanadium, are used to increase strength, ductility, hardness and toughness. e) Gasifiers - Minerals, such as fluorspar and limestone, are usually used to form a shielding gas in the self-shielded type wires.
How do magnets help generator produce electricity?
Magnets would have magnetic flux around. As a coil linked with this magnetic flux is rotated such that the flux would change then an electro motive force is induced. This is the way in which generator functions.

What is leakage factor?
The Ratio of the total flux ( flux in iron path) to the useful flux (flux in air gap)
Difference between leakage flux and mutual 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.
Difference between mutual flux and leakage flux?

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.
