Your question is unclear, but flux density is a function of the cross-sectional area of the magnetic circuit in which the magnetic flux is established.
Flux density (symbol: B) is defined as 'the flux per unit area'. If the flux is measured in webers (pronounced 'vay-bers') and the cross-sectional area is measured in square metres, then the flux density is measured in teslas(symbol: T) which is a special name given to a weber per square metre.

How the losses will reduce if you keep the flux density in high level in power transformer?
The flux density is set at the most the core material can stand, which for standard laminated transformer iron is around 1 Weber per square metre. Based on that and the cross-section area of the core, the volts per turn figure is calculated for both the primary and the secondary winding. If the operating voltage stays constant, so will the flux density and the iron losses.
How do you improve the flux linkage between the primary and secondary windings in a transformer?
by using an iron core
How does Lenz's Law explain power loss in transformers?
It doesn't, really. The power loss in transformers is broken down into copper loss and iron loss. The copper loss comes from the resistance of the windings in the transformer and depends on the load current, while the iron loss in the magnetic core depends on the magnetic flux density and is constant if the supply voltage is constant.
How can hysteresis loss in magnetic material may be reduced?
Hysteresis losses depend on the type of metal used to manufacture the magnetic circuit of a machine. Most magnetic circuits are made from silicon steel. Generally speaking, there's not much you can do to reduce hysteresis losses as that has already been factored in by the machine's designer.
How the voltage is induced in a single phase transformer?
The changing magnetic flux in the iron core of the transformer induces a voltage in the windings.

What is the function of the iron core in a transformer?
The iron core is there to provide a path for the magnetic flux to link both the primary and the secondary with as little flux as possible linking only one of the windings. The cross-section area of the core determines how much magnetic flux there is, because transformer iron has a fixed maximum flux density, usually 1 Weber per square metre. The amount of flux determines how many volts per turn there are on both windings.
What is leakage factor?
The Ratio of the total flux ( flux in iron path) to the useful flux (flux in air gap)
Why soft iron is placed in moving coil galvanometer?
1. to intensify the magnetic field by reducing the length of airgap across which the magnetic flux has to pass; 2. to give a radial magnetic flux of uniform density, thereby enabling the scale to be uniformly divided.
How does the density of iron vary with temperature?
Silver is more dense because silver is around 10.5g/cc, an iron around 7g/cc. silver atomic number 47, where as iron is 26. This means the nucleus will be much heavier, but also take up more space.
What is the density of galvanize iron?
The density of Galvanized Iron is 7850 kg/m3. Density of steel is equal to the density of galvanized iron
Does iron have low density?
No, the density of iron is fairly high.
Why does an iron ball sink and not an iron ship?
as relative density is directyy proportional to on surface area.... the iron ship being vast & having a huge surface area is able to float... whereas an iron ball being heavy & with less surface area sinks away..!
Why is density an important factor to know about a material?
density is how much matter is packed into one area. so the higher density the more likely it is to be heavier. for example, cork has a very low density and iron has a higher density.
Which has a higher density iron or silicon?
Iron is more dense than silicon.
Which has the greater density a kilogram of feathers of kilogram of iron?
Iron has a greater density.
Why is the sima layer found beneath the sial layer?
The sial layer has a lighter density than the sima layer, which is due to increased amount of aluminium, and decreased amount of iron and magnesium.
