Question

Write the dimensions of Magnetic flux in terms of mass, time, length and charge.

• A. $\left[M^1{L}^2{T}^{-1}{Q}^{-2}\right]$
• B. $\left[M^1{L}^2{T}^{-1}{Q}^{-1}\right]$
• C. $\left[M^1{L}^3{T}^{-1}{Q}^{-1}\right]$
• D. $\left[M^4{L}^2{T}^{-1}{Q}^{-1}\right]$

Answer 1

Answer: (B)

$\left[M^1{L}^2{T}^{-1}{Q}^{-1}\right]$

B. $\left[M^1{L}^2{T}^{-1}{Q}^{-1}\right]$

Dimension of magnetic field,

$\left[B\right]=\left[M^1{L}^0{Q}^{-1}\right]$

Dimension of surface Area,

$\left[A\right]=\left[L^2\right]$

The magnetic flux ,

$\varphi =B.A$

The dimension of magnetic flux in term of mass, time, length and charge,

$\left[\varphi \right]=\left[M^1{L}^2{T}^{-1}{Q}^{-1}\right]$
