Question

What is the dimensional formula for magnetic flux densities?

Answer 1

The expression relating the magnetic force (F) with magnetic field density (B) is:

$F=qvBsin\theta$

$\Rightarrow B=\frac{F}{qvsin\theta }$

The dimensional formulae for :

Force =$F=\left[ML{T}^{-2}\right]$

$v=\left[L{T}^{-1}\right]$

$q=\left[AT\right]$

and angle is dimensionless

$\therefore B=\left[M{L}^0{T}^{-2}{A}^{-1}\right]$
