Where are PMSM motors used?
PMSM motors are used in hybrid cars
Is there any device which can convert constant magnetic flux into variable flux?
A generator, in general.
Do magnetic flux in induction motor remains constant?
ni it doesn't
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.
What are industrial applications of DC shunt motors?
Dc shunt motor is a constant flux and constant speed motor . So that it is used in centrifugal pumps ,machine tools ,blowers and fans etc.

Is mutual flux in transformer constant for all loads?
The flux is set by the voltage applied to the transformer. In most applications, the voltage is constant, and therefore the flux is constant also.
Determine the effect of variable area to the magnetic flux within the solenoid at constant number of windings and current?
With constant number of windings and current, the magnetic field density of a solenoid remains constant. However, magnetic flux is determined by the flow of magnetic field force through a given area. Therefore, the area is linearly and directly proportional to the magnetic flux.
Flux in DC vary or constant.?
In DC or direct current, the flux is constant. AC or alternating current is variable.
Why using parks transformation in pmsm drive not clarkes transformation?
In PMSM drives both parks and clarkes transformations are used...

Why transformer is called constant flux machine?
when a load is connected to a transformer current(say I2) flows through secondary coil thus an M.M.F (N2I2) is produced ,this produces the secondary flux. This flux reduces the the main flux induced in the primary & also reduces E.M.F E1 in the primary As a result more current is drawn from the supply. This additional current drawn is due to the load component(say I2' ) This I2' is anti-phase with I2.This I2' sets a flux which opposes the secondary flux & helps the main flux. The load component flux neutralises the secondary flux produced by I2 .The M.M.F N1I2' balances N2I2.Thus the net flux is always at constant level. As practically flux is constant,the core loss is constant for all loads. Hence a transformer is always called a Constant Flux Machine.

Does constant magnetic flux in a coil induce a current in it?
Faraday's Law: the E.M.F. induced in a conductor [the current is caused by the E.M.F.] is directly propotional to the rate of change of magnetic flux linkage.A constant magnetic flux isn't changing, so the rate of change is zero and the induced E.M.F is zero. No E.M.F. = no current.
