![]() ![]() If the frequency increases the flux density decreases and vice verse My doubt is that is my conclusion is correct?. That is the relation between flux density and frequency is inversely proportional. I had heard there is a relation between flux density and frequency. v= 4.44n.f.flux n= no of turns of winding you said flux is inversely prop to freq which us true but not entirely in electric machines we increase freq but at the same time we have to decrease voltage.v/f= fkux.which have to be const.bcoz we design machines to work at const flux.increase influx saturate the core and decrease in flux reduce flux density which reduce generated voltage. When the Rotating Air Gap block is in the faulted state, you can apply a reduction factor to the flux density of any of the rotor poles by specifying the Faulted rotor pole flux multipliers parameter. The flux density associated with each rotor magnet remains sinusoidal in shape. However, it's perfectly possible that in certain electronic DEVICES, higher frequency decreases flux density, etc. A fault is defined as a reduction in the peak magnet flux density. The two quantities are not interdependent in any such way, although the frequency of oscillations in magnetic flux density would drive the frequency of everything else in a circuit. Of turns No such relationship arises from physics alone. Where B(flux density) =flux/unit area, F= frequency, T= no. This relation comes from e.m.f equation of a transformer. The magnetic anisotropy is a non-linear phenomenon in relation to magnetizing frequency as well as to flux density. This is why highly portable electrical equipment is sometimes designed to operate at 400 Hz rather than the more common 60Hz- it reduces the amount of iron required for transformer cores. Increasing with peak flux density dispersion of ratio P h /P ex for angle x 54° can result from relatively low saturation at this magnetisation direction. As frequency increases, the integration period is shorter and thus the peak flux created is diminished. This results from Faraday's law which shows that the magnetic flux is proportional to the time integral of the applied voltage. If you happen to be talking about an inductor or a transformer, then as the frequency of the AC input increases and with other things being equal, the maximum flux density created by the excitation current will diminish. and vice versa You need to be more specific about the context of your question. Flux Φ = V/f.hence : V = constant = Φ*f the higher the flux, the lower the frequency. ![]()
