define magnetic flux

Hey !!
MAGNETIC FIELD
The magnetic flux is defined in magnetic field in the same way as the electric flux in an electric field.
Let me give a brief explanation of magetic flux
Consider a small surface of area A. Let n be the unit vector which is drawn normal to the surface. If 'θ' is the angle between n and the uniform magnetic field B(bar) then the magnetic flux (Ф) through the surface is defined as
Ф = B(bar) . A(bar) = (B(bar) , n(cap) A
where n(bar) = unit vector along the normal drawn to the plane of the surface.
A = Area of the magnetic field bounded by the surface.
Ф = (B cos θ) A
Now B cos θ is the component of the magnetic field normal to the plane of the surface and can be represented as Bn. Hence Ф = BnA
Thus, magnetic flux over a given surface is defined as the product of the area of the surface and the component of the magnetic field normal to the surface (Bn)
SI UNIT OF MAGNETIC FLUX IS ''Weber'' (Wb)
CGS UNIT OF FLUX IS ''Maxwell'' (Mx)
1 WEBER = 1 tesla-meter²
1 WEBER = 10⁸ maxwell
DIMENSIONAL FORMULA OF THE MAGNETIC FLUX IS ''ML²T⁻²A⁻¹''
MAGNETIC FLUX IS ''Scalar''
GOOD LUCK !!
Answer:
The number of magnetic lines of forces set up in a magnetic circuit is called Magnetic Flux.
It is analogous to electric current, I in an electric circuit.
Its SI unit is Weber (Wb)
Its CGS unit is Maxwell.
It is denoted by φm.
