What is the relation between magnetic flux density and magnetic field?
The definition of H is H = B/μ − M, where B is the magnetic flux density, a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area; μ is the magnetic permeability; and M is the magnetization.
What is the difference between the magnetic field and 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.
What is magnetic flux density symbol?

Is magnetic field and magnetic induction same?
Most textbooks on electricity and magnetism distinguish the magnetic field H and the magnetic induction B. Yet, in practice physicists and chemists almost always call B the magnetic field, which is because the term “induction” suggests an induced magnetic moment.
What do you mean by flux and flux density in magnetic field?
Magnetic Flux Density is amount of magnetic flux through unit area taken perpendicular to direction of magnetic flux. Flux Density (B) is related to Magnetic Field (H) by B=μH. The total number of magnetic field lines passing through a given area normally is called magnetic flux.
How do you vary magnetic flux density?
There are three ways to change the magnetic flux through a loop:
- Change the magnetic field strength (increase, decrease) over the surface area.
- Change the area of the loop (increase by expanding the loop, decrease by shrinking the loop)
What is a magnetic field flux density?
The magnetic flux density or magnetic induction is the number of lines of force passing through a unit area of material, B. The unit of magnetic induction is the tesla (T).
What is meant by magnetic flux density?
magnetic flux density. A vector quantity measuring the strength and direction of the magnetic field around a magnet or an electric current. Magnetic flux density is equal to magnetic field strength times the magnetic permeability in the region in which the field exists.
What is the density of magnetic field?
magnetic fields The energy density in a magnetic field is given in the absence of matter by 1/2B2/μ0; it is measured in units of joules per cubic metre. The total magnetic energy can be obtained by integrating the energy density over all space. The direction of the magnetic…
What is the difference between magnetic flux and magnetic flux density?
Some people use these terms interchangeably. But they have different and particular meanings. The main difference between magnetic flux and magnetic flux density is that magnetic flux is a scalar quantity whereas magnetic flux density is a vector quantity. Magnetic flux is the scalar product of the magnetic flux density and the area vector.
What are the physical quantities of magnetism?
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.
What are the two different attributes of a magnetic field?
In physics, there are two different attributes of a magnetic field: The “magnetic field strength”. Usually given the symbol H. Measured in amps per metre (A/m). The “magnetic flux density”. Usually given the symbol B. Measured in teslas (or microteslas or gauss).
What is the SI unit of magnetic flux?
The SI unit of magnetic flux is the Weber. Flux density is magnetic flux divided (vectorially if it is at an angle) by the area of the surface in tesla units. Electrical current in human-made wiring flows through insulated conductors.
