# Flux Density And Field Strength

• ### 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 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

02/12/2015· 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...

### Difference between magnetic field strength and flux density?

Here, is the magnetic field due to a magnetic material, like a bit of iron, or some other material that can be magnetised it's just the usual quantity that causes magnetic effects. We're imagining a bit of iron sitting in the B field of a wire, and measuring the total B field near to (or inside of) the bit of iron. There are two components to the total B field:

### Magnetic Fields and Induction Physics A-Level

Magnetic Flux Density, B "Magnetic flux density, B, is the force, F, per unit length, l, per unit current, I, on a current carrying conductor at right angles to the magnetic field. It is otherwise known as the magnetic field strength. The unit of measurement is the tesla (T)".

26/04/2016· 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.

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

So for ferromagnetic materials the ratio of flux density to field strength ( B/H ) is not constant but varies with flux density. However, for air cored coils or any non-magnetic medium core such as woods or plastics, this ratio can be considered as a constant and this constant is known as μ o, the permeability of free space, ( μ o = 4.π.10-7 H/m ).

### Magnetic Flux Density

The magnetic flux density is measured in Webers per square meter [Wb/m^2], which is equivalent to Teslas [T]. The B field is a vector field, which means it has a magnitude and direction at each point in space. We know that a particle with a charge q [C] will experience a force when in the presence of an Electric Field E.

### Difference Between Magnetic Field and Magnetic Flux

07/10/2015· 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, If the term “magnetic field” is used to refer to a quantity rather than a region, it is most likely referring to the magnetic field strength.

### Magnetism: quantities, units and relationships

Magnetic field strength cannot be measured in the same way because there is no 'magnetic monopole' equivalent to a test charge. Do not confuse magnetic field strength with flux density, B. This is closely related to field strength but depends also on the material within the field. The strict definition of H is

### Magnetic Field Strength Flux Density Magnetism

The flux can be distributed widely, producing and extended and weak field, or it could be very concentrated, resulting in a strong compact field. There are two measurable parameters that are effected by the flux distribution, these are field strength and flux density. Field strength. A larger m.m.f. will naturally produce a stronger field. With

### Magnetic field Wikipedia

In the International System of Units, H, magnetic field strength, is measured in the SI base units of ampere per meter. B, magnetic flux density, is measured in tesla (in SI base units: kilogram per second 2 per ampere), which is equivalent to newton per meter per ampere. H and B differ in how they account for magnetization.

### Permeability Flux Density & Field Strength Magnetism

However, rather than just being a measure of the ratio of the m.m.f. to the flux it produces, permeability takes into account the distribution of the flux within the material. Permeability is the ratio of the flux density of the magnetic field within the material, to its field strength. u =B/H .

### Difference Between Magnetic Field & Magnetic Flux

Difference Between Magnetic Field & Magnetic Flux The most significant difference between the magnetic field and the magnetic flux is that the magnetic field is the region around the magnet where the moving charge experiences a force, whereas the magnetic flux shows the quantity or strength of magnetic lines produced by the magnet. The other differences between the magnetic field and

### Relationship between flux density and field strength

23/08/2014· In simple terms, if flux density increases, then field strength increases and vice versa. The flux density is equivalent to field strength times with a variable.

### Linking Magnetic Flux Density and Magnetic Field

### What's the difference between magnetic flux density,B

10/08/2012· 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.

### Copper and electricity. Flux and flux density.

Magnetic flux density: You can think of the flux as being represented by the number of field lines. We sometimes call them lines of magnetic flux. The closer together the lines of flux, the stronger the field. That is, the strength of the field is represented by the density of the lines of flux.

### Difference between 'magnetic field strength' and

22/10/2011· I've seen another term for magnetic field strength and that is "magnetic flux density". You can sort of think of magnetic flux as the "amount of field lines" passing through an area. Density should remind you to the fact that these field lines may be closer together in an area or they may be further apart. So in this way, it is the same thing as magnetic field strength.

### Hirst Magnetic Instruments Ltd

The two main magnetic field properties of magnets which are normally measured are magnetic flux density and magnetic flux. To explain the difference between the two consider the magnets below: Magnet A is smaller than magnet B. They both have the same “magnetism”, that is the same amount of total flux. As A has a smaller surface area than B

### Difference Between Magnetic Field and Magnetic Flux

14/06/2011· The density of magnetic flux lines is deeply related to the strength of magnetic field. As they are directly proportional, we can assume the strength of magnetic field with the density of magnetic flux lines. These flux lines are the densest at magnetic poles, and as one moves away from the poles, the magnetic flux lines diverge and become less
