Dimensional formula of magnetic flux is
A$M{L^2}{T^{ - 2}}{A^{ - 1}}$
B$M{L^0}{T^{ - 2}}{A^{ - 2}}$
C${M^0}{L^{ - 2}}{T^{ - 2}}{A^{ - 3}}$
D$M{L^2}{T^{ - 2}}{A^3}$
(IIT-1982) (AIPMT-1999)
Solution
(a) $\phi = BA = \frac{F}{{I \times L}}A $
$= \frac{{[ML{T^{ – 2}}]\,\,[{L^2}]}}{{[A]\,\,[L]}} $
$= [M{L^2}{T^{ – 2}}{A^{ – 1}}]$
$= \frac{{[ML{T^{ – 2}}]\,\,[{L^2}]}}{{[A]\,\,[L]}} $
$= [M{L^2}{T^{ – 2}}{A^{ – 1}}]$
