'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

How do you calculate the pole strength of a magnetic?
The pole strength of a magnetic can be calculated by measuring the magnetic flux that it produces and dividing it by the area of the pole face. The formula to calculate the pole strength is: Pole Strength = Magnetic Flux / Area of pole face.
What does symbol B mean in physics?
In physics, symbol B is often used to represent magnetic field. Magnetic fields are vector quantities that exert a force on moving electric charges and magnetic materials. This symbol is commonly used in equations involving electromagnetic phenomena.
What is the importance of air gap in magnetic circuit?
The air gap in a magnetic circuit is important because it increases the reluctance of the circuit, which in turn influences the magnetic flux and magnetic field strength. By controlling the size of the air gap, we can control the level of magnetic flux and magnetic force produced in the circuit. This can be useful in applications where precise control over magnetic properties is required.
Is the unit of magnetic flux equal to Vs?
The SI unit for magnet flux is (Wb) weber. However, if the magnet flux variation in 1 second, produces 1 V of electromotive force in a coil, this flux will correspond to 1 Wb. Therefore, 1Wb = 1 Vs (voltage-second).
What makes a material diamagnetic?
A material is diamagnetic if it contains no unpaired electrons and all its electrons are in filled orbitals, leading to no net magnetic moment. When exposed to a magnetic field, diamagnetic materials will generate their own magnetic field in the opposite direction, causing a weak repulsion.
What is Magnetic flux density unit?
"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 you calculate the change in magnetic flux?
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)
How do you calculate total flux when flux density and magnetic field strength has been?
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
What is flux density related to?
In case of electrostatics, flux density = electric field intensity and in case of magnetism, flux density = magnetic field induction
What is the flux linkage formula used to calculate the total magnetic flux passing through a coil of wire?
The flux linkage formula used to calculate the total magnetic flux passing through a coil of wire is given by the equation N, where represents the magnetic flux, N is the number of turns in the coil, and is the magnetic flux per turn.
Magnetic flux density can be measured by using?
Gaussmeter
Which quantity has unit Tesla?
Magnetic flux density.
Unit of magnetism are?
The unit of magnetism are: Weber for magnetic flux, Tesla for magnetic flux density and ampere per meter for magnetic field strength.
How do you calculate flux density?
1yards = ? meters
What is flux density?
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'.
What is the limit for magnetic field developed for a DC machine?
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.
What happens to the sideways force when flux density increases?
When flux density increases, the force experienced by a current-carrying conductor due to a magnetic field (sideways force in this case) will also increase. This is because the force is directly proportional to the magnetic flux density and the current in the conductor.
