The dimensional formula of magnetic flux is

Options:

Answer:

Solution:

The magnetic flux linked with a surface,

$ϕ = B A \cos θ$

Since $B = F / q v,$

$ϕ = \frac{F}{q v} A cos θ = \frac{F}{(I \times t) v} A cos θ$

$\Rightarrow \frac{[{MLT}^{-2} L^{2}]}{[{ATLT}^{- 1}]} = [{ML}^{2} T^{-2} A^{- 1}]$
