J & K CETJ & K CET 2015Physical World, Units and Measurements

Solution:

Magnetic flux $(\phi)=($ Magnetic field) $) \times($ Area $)$ or $[\phi]=[B][A]$
$=\frac{[\text { Force }][\text { Area }]}{[\text { Current }][\text { Length }]}=\frac{\left[M L T^{-2}\right]\left[L^{2}\right]}{[A][L]}$
$|\phi|=\left[M L^{2} T^{-2} A^{-1}\right]$
