Q. Dimensional formula of magnetic flux is
A) $ML^{2}T^{- 2}A^{- 1}$
B) $ML^{0}T^{- 2}A^{- 2}$
C) $M^{0}L^{- 2}T^{- 2}A^{- 3}$
D) $ML^{2}T^{- 2}A^{3}$
Explanation
$\phi = BA = \frac{F}{I \times L}A = \frac{\left\lbrack MLT^{- 2} \right\rbrack\left\lbrack L^{2} \right\rbrack}{\lbrack A\rbrack\lbrack L\rbrack} = \lbrack ML^{2}T^{- 2}A^{- 1}\rbrack$
