'Magnetic field strength' (symbol: H) is defined as 'the magnetomotive force, per unit length, of a magnetic circuit'. In SI, it is expressed in amperes per metre (A/m), which is often spoken as "'ampere turns' per metre".
It's equation is: H = (IN) / l
where:
H = magnetic field strength (ampere per metre)
I = current flowing through coil (amperes)
N = number of turns in coil
l = length of magnetic circuit
Magnetic field strength in a coil can be measured from the equation :-F=I*B*L Where, f=magnitude of Lorentz Force I=Current Flowing Through the Coil L=Length of the wire THE UNIT MAGNETIC FIELD STRENGTH IS 'TESLA' or Weber per metre sq.
Magnetic field strength is defined as the magnetomotive force per unit length, and its SI unit of measurement is the ampere per metre (usually spoken as 'ampere-turn per metre').
in the mosfet why in the substrate have there hole and electrons.The formula is E=F/Q
the poles of an electric motor have a cross sectional area of 2.5mm2. calculate the magnetic flux density in the pole when the total magnetic flux is 0.25Wb?
Electric field intensity= force/charge
L-1a1
Magnetic flux density, expressed in teslas in SI.
All materials naturally repel magnetic lines of flux but some materials, like iron, are attracted to magnetic flux because they have unpaired electrons that are attracted to the lines of flux.
there is no force on the wire as the magnetic flux density on both sides of the conductor is the same. So, there is no net force on the wire

Magnetic flux through a surface is maximum when the direction of the magnetic field is in the same direction as the normal vector of the surface. In other words, the magnetic flux is maximum when the magnetic field is perpendicular to the surface area. That's why φ=BAcosθ, where θ is the angle between the direction of the magnetic field and the normal vector of the surface area. When the magnetic field is exactly the same direction as the normal vector (aka the magnetic field is perpendicular to the surface), θ=0 and cosθ = 1, its maximum value. The closer θ is to 90 degrees (ie. the more parallel the direction of the magnetic field is to the surface area, or the less parallel the magnetic field is to the surfaces normal vector), the smaller cosθ is, and thus flux will decrease accordingly.
"Magnetic flux density" is also known as the magnetic field,The SI unit for this is the Tesla, written as T.CommentMagnetic flux density is not "also known as the magnetic field". It describes the intensity of a magnetic field.
How do i calculate the delta of the Spell check your answer equation,emf=-N(delta.BA/delta.t) always subtract larger value from smaller one if both initial and final flux is given,secondly you can use phi=B.Acos theta (ref:roger muncaster A-level phy)
once flux density is known multiply to it the area perpendicular to the flux lines . the product is the total flux passing through the area. If field strength is known , get the flux density by pultiplying to it the permeability of the medium. then flux can be obtained as above. from : govind Kunkolienker kunkolienker@yahoo.com
In case of electrostatics, flux density = electric field intensity and in case of magnetism, flux density = magnetic field induction
suggestion of the improvement in experiments magnetic flux?

Magnetic flux density.
Magnetic flux density is measured in tesla.Magnetic flux is measured in weber.
The unit of magnetism are: Weber for magnetic flux, Tesla for magnetic flux density and ampere per meter for magnetic field strength.
Something that which produces a magnetic fieldThe magnetic field that surrounds a magnet is made up of magnetic flux (symbol, the Greek letter 'phi'), usually represented as lines in field diagrams. The SI unit for measuring magnetic flux is the weber (pronounced 'vay-ber'). The intensity of this flux (the closeness of the lines in diagrams) is called the flux density (symbol: B). Flux density is greatest in the areas nearest a magnet's poles. Flux Density is defined as 'flux per unit area', and is measured in webers per square metre which, in SI, is given the special name, the 'tesla'.
1yards = ? meters
The magnetic field used in machines is quantified in terms of its flux density (symbol: B), expressed in teslas. The flux density is established by the magnetic field strength (H), expressed in amperes per metre, set up in the field windings.As the magnetic field strength increases, the flux density increases until it reaches saturation. This is the point when the magnetic domains within the magnetic circuit are all aligned. At this point, any further increase in magnetic field strength will fail to increase the flux density.So saturation of the magnetic circuit limits the flux density of the field.
