Mathematically it is represented as B = Φ/A where B is magnetic flux density in teslas (T), Φ is magnetic flux in webers (Wb), and A is area in square meters (m 2 ). The SI unit for magnetic flux density is the tesla which is equivalent to webers per square meter.
What is magnetic 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). ... This relationship is used in high-gradient magnetic separation (discussed further in Section 13.4.
How do you calculate magnetic flux?
ΦB=B⋅A=BAcosθ Φ B = B ⋅ A = BA cos , where B is the magnitude of the magnetic field (having the unit of Tesla, T), A is the area of the surface, and θ is the angle between the magnetic field lines and the normal (perpendicular) to A.
How do you calculate magnetic flux example?
ΦB=B⋅A=BAcosθ Φ B = B ⋅ A = BA cos , where B is the magnitude of the magnetic field (having the unit of Tesla, T), A is the area of the surface, and θ is the angle between the magnetic field lines and the normal (perpendicular) to A.
What is the formula of magnetic flux density?
| Quantity Unit Formula | Magnetic flux density webers per metre 2 B = Φ /Area | Electric flux density coulombs per metre 2 D = C/Area |

What is SI unit of flux?
Weber , unit of magnetic flux in the International System of Units (SI), defined as the amount of flux that, linking an electrical circuit of one turn (one loop of wire), produces in it an electromotive force of one volt as the flux is reduced to zero at a uniform rate in one second.
What is flux unit?
1. flux unit – a measure of the strength of a magnetic field per unit area . magnetic flux unit. magnetic flux – a measure of the strength of a magnetic field over a given area. maxwell, Mx – a cgs unit of magnetic flux equal to the flux perpendicular to an area of 1 square centimeter in a magnetic field of 1 gauss.
Is flux a density?
Conceptually, electric flux can be thought of as “the number of field lines” passing through a given area. ... (Electric flux density is the electric flux per unit area , and is a measure of strength of the normal component of the electric field averaged over the area of integration.
What is magnetic flux and its unit?
Magnetic flux is what generates the field around a magnetic material. ... The number of magnetic field lines passing through a surface (such as a loop of wire). The magnetic flux through a closed surface (such as a ball) is always zero. The SI unit of magnetic flux is the Weber (Wb) (in derived units: volt-seconds).
What is magnetic flux Class 10?
Magnetic flux refers to the total number of magnetic field lines penetrating any surface placed perpendicular to the magnetic field . It is calculated as the product of the average magnetic field strength and the perpendicular area it penetrates.
When magnetic flux is maximum?
The magnetic flux through the plane of the coil has its maximum value when this plane is perpendicular to the magnetic field lines between the poles . As the coil turns and the plane of the coil becomes parallel to the field lines, the flux becomes zero.
Can we see magnetic flux lines?
At each end of a magnet is a pole. These lines of flux (called a vector field) can not be seen by the naked eye, but they can be seen visually by using iron fillings sprinkled onto a sheet of paper or by using a small compass to trace them out .
What is the magnetic flux through the square?
The concept of Faraday’s Law is that any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be “induced” in the coil. ... Magnetic flux F is defined by F=BA where B is the magnetic field or average magnetic field and A is the area perpendicular to the magnetic field.
What is the SI unit of dipole moment?
The SI composite unit of electric dipole moment is the ampere second meter .
What is SI unit of inductance?
The henry (symbol: H) is the SI derived unit of electrical inductance.
What is the SI unit of permittivity?
The SI composite unit of electric permittivity is the farad per meter .
