# flux density and field strength relationship

• ### Hysteresis | physics | Britannica.com

When the magnetizing field is diminished, the magnetic flux density decreases, again lagging behind the change in field strength H. In fact, when H has decreased to zero, B still has a positive value called the remanence , residual induction , or retentivity, which has a high value for permanent magnets.

The magnetic field strength (the magnetic flux density) can be defined using the force felt by a particle of charge travelling through it at a velocity : If the magnetic field is perpendicular to the direction of particle’s motion, then we have,

• ### Magnetic field strength dependent on distance from source

Aug 01, 2013· I am trying to find an equation that tells the strength of a magnetic field a given distance away from the source. Magnetic field strength dependent on distance from source Page 1 of 2 1 2 section for the current loop (note that this does not fit within the described diameter), this corresponds to a current density of 600kA/mm^2 or 6*10

• ### What is magnetic field strength? - Definition from

Magnetic field strength is one of two ways that the intensity of a magnetic field can be expressed. Technically, a distinction is made between magnetic field strength H, measured in amperes per meter (A/m), and magnetic flux density B, measured in Newton-meters per ampere (Nm/A), also called teslas

• ### Difference Between Magnetic Flux and Magnetic Flux Density

Main Difference – Magnetic Flux vs Magnetic Flux Density. In magnetism, several physical quantities such as magnetic flux, magnetic flux density and magnetic field strength are used to explain the behaviors or influences of magnetic fields.Some people use these terms interchangeably. But they have different and particular meanings.

• ### Theory of Electromagnetic Fields - arXiv

Theory of Electromagnetic Fields Andrzej Wolski University of Liverpool, and the Cockcroft Institute, UK The ﬁelds B~(magnetic ﬂux density) and E~(electric ﬁeld strength) determine the force on a particle of charge qtravelling with velocity ~v(the Lorentz force equation): F~= q

• ### Magnetic flux - Wikipedia

If the magnetic field is constant, the magnetic flux passing through a surface of vector area S is where B is the magnitude of the magnetic field (the magnetic flux density) having the unit of Wb/m 2 , S is the area of the surface, and θ is the angle between the The relationship is given by Faraday''s law: =

• ### What is the physical difference between magnetic flux

What is the physical difference between magnetic flux density (B) and magnetic field strength (H)? Update Cancel. What is the relationship between magnetic flux density and magnetic field? What is difference between Magnetic Induction (magnetic field strength) and Flux Density? Is E (Electric Field Strength) more analogous to

• ### Relationship between flux density and field strength - Answers

In simple terms, if flux density increases, then field strengthincreases and vice versa. The flux density is equivalent to fieldstrength times with a variable.

• ### Relationship between flux density and field strength -

In simple terms, if flux density increases, then field strengthincreases and vice versa. The flux density is equivalent to fieldstrength times with a variable.

• ### Magnetic Field Intensity, Flux Density, Physics -

May 19, 2013· Magnetic Field Intensity, Flux Density, Physics Magnetic field strength (H) is the amount of magnetizing force. It is proportional to the length of

• ### Magnetic field - Wikipedia

The direction of the magnetic field at any point is parallel to the direction of nearby field lines, and the local density of field lines can be made proportional to its strength. Magnetic field lines are like streamlines in fluid flow , in that they represent something continuous, and a different resolution would show more or fewer lines.

• ### Magnetic Hysteresis Loop including the B-H Curve

The set of magnetisation curves, M above represents an example of the relationship between B and H for soft-iron and steel cores but every type of core material will have its own set of magnetic hysteresis curves. You may notice that the flux density increases in proportion to the field strength until it reaches a certain value were it can not increase any more becoming almost level and

• ### Relationship Between Flux Density (B) And Field Strength

the question is : describe the relationship between flux density (B) and field strength (H)?? for high school

• ### relationship between flux density and magnetic field strength

Magnetic Field Strength. The magnetic fields generated by currents and calculated from Ampere''s Law or the B from H, B is sometimes called the magnetic flux density or the magnetic induction. Another commonly used form for the relationship between B and H is »More detailed

• ### Magnetic Flux and Magnetic Permeability - Physics Tutorials
