Derive dimension and SI unit of magnetic flux.

1.	Derive dimension and SI unit of magnetic flux.
Answer» Like electric,flux, magnetic flux is proportional to the number of magnetic field lines passing through a surface. It is denoted by ϕ_B. Mathematically, ϕ_B = vector(B . A) = B .A cos 0 Where ϕ_B is the magnetic flux through a plane surface of area A placed in a uniform magnetic field B.θ is the-angle between (vector B and vector A). Equation (i) can be extended-to curve surfaces and non-uniform fields. S .I. unit of magentic flux is weber (Wb) 1 Wb = 1 tesla. m² The dimensional formula of magnetic flux is [ML²T^-2A^-1].

Like electric,flux, magnetic flux is proportional to the number of magnetic field lines passing through a surface. It is denoted by ϕ_B.

Mathematically, ϕ_B = vector(B . A) = B .A cos 0

Where ϕ_B is the magnetic flux through a plane surface of area A placed in a uniform magnetic field B.θ is the-angle between (vector B and vector A). Equation (i) can be extended-to curve surfaces and non-uniform fields.

S .I. unit of magentic flux is weber (Wb)

1 Wb = 1 tesla. m²

The dimensional formula of magnetic flux is [ML²T^-2A^-1].
