Feb 18, 2014· Field strength is the potential of creating the flux density. Flux density is dependent on the material and hence permeability of the material. Field strength depends on current and number of turns per unit length while Flux density depends on this as well as the material.
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 Question Is : Describe The Relationship Between Flux Density (B) And Field Strength (H)?? For High School 14:12 Fri 05th Jul 2013 6 answers, last by Peter Pedant 23:23 Fri 05th Jul 2013
The magnetic flux Φ is the magnetic flux density which runs through an imagined area. If the field lines run in a straight line (e.g. between the poles of a horseshoe magnet), the magnetic flux Φ through a certain area A which runs vertically to the flux can be calculated as follows:

By plotting measured values of flux density B against magnetic field strength H, a magnetisation curve (or B–H curve) is produced. For non-magnetic materials this is a straight line. Typical curves for four magnetic materials are shown in Figure 10.11.
The relationship is defined by the magnetic permeability ... 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.
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
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.
If the magnetic field strength is then reduced, the flux density will also reduce (again, not linearly), but when the magnetic field strength reaches zero amperes, a certain amount of flux density...
Permeability is the ratio of the flux density of the magnetic field within the material, to its field strength. u =B/H . u = the permeability of the material measured in Henries per metre (Hm-1). B = flux density measured in Tesla (T). H = the field strength measured in .
Magnetic Field Strength H ... To further distinguish B from H, B is sometimes called the magnetic flux density or the magnetic induction. The quantity M in these relationships is called the magnetization of the material. Another commonly used form for the relationship between B and H is .
By plotting measured values of flux density B against magnetic field strength H, a magnetisation curve (or B–H curve) is produced. For non-magnetic materials this is a straight line. Typical curves for four magnetic materials are shown in Figure 10.11.
Jun 30, 2020· Magnetic field strength, also called magnetic intensity or magnetic field intensity, the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. It is expressed as the vector H and is measured in units of amperes per metre. The definition of H is H = B/μ − M, where B is the magnetic flux density, a measure of the actual ...
Flux Density And Field Strength Relationship - Stone Crusher . Magnetic field, field strength, and flux density. Sometimes, people will be very precise and talk about either the magnetic flux density or the magnetic field ...
A magnetic field is a vector field (more precisely a pseudovector field) that describes the magnetic influence of electric charges in relative motion and magnetized materials. A charge that is moving parallel to a current of other charges experiences a force perpendicular to its own velocity. The effects of magnetic fields are commonly seen in permanent magnets, which pull on magnetic ...
Magnetic Flux Density Flux density is the measure of the number of magnetic lines of force per unit of cross-sectional area. While the total amount of the flux produced by a magnet is important, we are more interested in how dense or concentrated, the flux is per unit of cross-sectional area.
A hysteresis curve is a plot, graph or some kind of pictorial representation of the relationship between the magnetic field strength (H) and the magnetic flux density (B) of a material under ...
The Hysteresis Loop and Magnetic Properties . A great deal of information can be learned about the magnetic properties of a material by studying its hysteresis loop. A hysteresis loop shows the relationship between the induced magnetic flux density (B) and the magnetizing force (H).It is often referred to as the B-H loop.
Magnetic field – Wikipedia, the free encyclopedia. 6 Relation between H and B .. Magnetic flux density; Magnetic induction; Magnetic field ... With the definition of m as the pole strength times the distance between the poles, this leads to τ = μ0mHsinθ, where μ0 is a .
