There are several quantities and related magnetic terms magnetic field strength magnetic flux density magnetisation polarisation magnetic flux and also magnetic field Under certain conditions the practical differences between some of these quantities are small
Magnetic Field Strength H The magnetic fields generated by currents and calculated from Ampere s Law or the Biot-Savart Law are characterized by the magnetic field B measured in Tesla But when the generated fields pass through magnetic materials which themselves contribute internal magnetic fields ambiguities can arise about what part of the field comes from the external currents and what
Aug 10 2012· The magnetic field strength H should not be confused with the magnetic flux density B the flux density is the field strength per area through which it is measured The magnetic flux Ф is simply the total flux sans any reference to the area in which it exists
Jun 14 2011· The relation between magnetic field and magnetic flux is given by the following equation B = u X H = uH Where B is the magnetic flux H is the density of magnetic field and u is the permeability of the medium There is another equation relating magnetic flux and magnetic field Magnetic Flux = B X A =BA
Jan 17 2012· The flux is not enough to understand the true nature of a given field The best way to describe a field is the flux density Flux density gives the amount of the field passing through a unit area for the given surface Flux density is also known as field intensity Even though the term flux is a conceptual term the flux density has a numerical
Magnetic field strength H is nothing but amount of magnetising force This magnetising force is directly proportional to current carried by the conductor and length of conductor Magnetic flux density B is nothing but amount of magnetic force
w wang 46 Magnetic susceptibility and permeability In large class of materials there exists a linear relation between M internal magnetization and H external applied magnetic field M = χH χ is positive then the material is called paramagnetic χis negative then the material is diamagnetic A linear relationship also occurs between B magnetic flux density
Magnetic flux density formula - Physics See also Difference between electric field and magnetic field The Gauss Although the Tesla T is the SI unit for the unit for flux density another unit is called the gauss from the CGS centimeter-gram-second system which is sometimes used 10 4 gausses = 1 T
Jun 16 2015· The relationship between flux density and magnetic field strength is therefore written as B = µH In this equation B is the flux density H is the magnetic field strength and µ is the magnetic permeability of a material When produced in a full B H curve it is apparent that the direction in which H is applied affects the graph
The number of magnetic flux lines which go through the unit area perpendicular to magnetic field is called Flux density B The relation between Magnetic strength H and flux density B can be defined by B = μH μ in this case is permeability the unit of magetizability In the air μis usually about 1 except special case and 1 Gauss ≒ 1

Simply put Gauss represents the number of magnetic field lines per square centimetre emitted by a magnet The higher the value the more lines of magnetism emitted by the magnet When a Gauss rating is displayed this can either be a measure of open circuit flux density or closed circuit flux density which is also referred to as remanence
The Magnetic Field Intensity or Magnetic Field Strength is a ratio of the MMF needed to create a certain Flux Density B within a particular material per unit length of that material c Its unit H = At m ampere-turns per meter Often N is used as the number of turns of wire around a core or magnetic …
Sometimes people will be very precise and talk about either the magnetic flux density or the magnetic field strength But actually magnetic field is perfectly valid as a description of either - both the magnetic flux density and the magnetic field strength are examples of a magnetic field And just using magnetic field is a lot simpler
