What is the dimension and SI unit of magnetic flux?
The Dimension of Magnetic Flux. The symbol which is used to denote the magnetic flux is ‘Φ’ or ‘ΦB’. Maxwell is the centimeter–gram–second (CGS) system of the unit for magnetic flux. Wb or Weber is the SI unit of magnetic flux.
What is dimension of magnetic flux density?
Magnetic Flux Density is the amount of magnetic flux through unit area taken perpendicular to direction of magnetic flux. Mathematically, b=φBA. Thus, the dimensional formula of magnetic flux density is b=φBA=[M1L2T−2I−1][L2]=[M1T−2I−1].
How do you find the dimension of flux?
The unit of electric field is Vm.
- Hence dimension of electric field is [MLT−3I−1]
- The electric flux is given in unit Nm2C−1.
- Hence dimension of electric flux is [ML3T−3I−1]
What are the SI units of magnetic flux?
The SI unit of magnetic flux is the weber (Wb; in derived units, volt–seconds), and the CGS unit is the maxwell.
How many dimensional formula are there?

What is the SI unit of the magnetic flux Weber?
1 Wb ≘ 1×108 Mx. In physics, the weber (/ˈveɪb-, ˈwɛb. ər/ VAY-, WEH-bər; symbol: Wb) is the SI derived unit of magnetic flux. A flux density of one Wb/m2 (one weber per square metre) is one tesla. The weber is named after the German physicist Wilhelm Eduard Weber (1804–1891).
What is magnetic flux formula and unit?
The magnetic field vector B is defined by the force it would apply to a charge moving in it. B = F/qv, so the units are (N *s) / (C *m), which we call a Tesla, or T. This is also called flux density. Flux is then given by B*A, so it is in T*m^2, which we also call a Weber.
What is dimensions and dimensional formula?
DIMENSIONS are the powers to which the fundamental quantities are raised to represent other physical quantities. DIMENSIONAL FORMULA is an expression in which dimensions of a physical quantity is represented in terms of fundamental quantities.
How do you calculate magnetic flux?
First,determine the magnetic field. Measure the strength of the magnetic field.
What is the magnetic flux equation?
Magnetic flux is a measure of the number of magnetic field lines passing through an area. The symbol we use for flux is the Greek letter capital phi, .The equation for magnetic flux is: , (Equation 20.1: Magnetic flux) where is the angle between the magnetic field and the area vector .
What is the SI unit for magnetic flux?
Weber (unit) In physics, the weber /ˈveɪbər/ (symbol: Wb) is the SI unit of magnetic flux.
What does magnetic flux mean in physics?
In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or ΦB. The SI unit of magnetic flux is the weber (Wb; in derived units, volt-seconds), and the CGS unit is the maxwell.
