    The dimensional formula of magnetic flux is :

    A)  \[\text{ }\!\![\!\!\text{ M}{{\text{L}}^{\text{2}}}{{\text{T}}^{\text{-1}}}{{\text{A}}^{\text{3}}}\text{ }\!\!]\!\!\text{ }\]                          

    B) \[\text{ }\!\![\!\!\text{ }{{\text{M}}^{0}}{{\text{L}}^{-2}}{{\text{T}}^{-2}}{{\text{A}}^{-2}}\text{ }\!\!]\!\!\text{ }\]

    C) \[\text{ }\!\![\!\!\text{ M}{{\text{L}}^{\text{0}}}{{\text{T}}^{\text{-2}}}{{\text{A}}^{\text{-2}}}\text{ }\!\!]\!\!\text{ }\]                          

    D) \[\text{ }\!\![\!\!\text{ M}{{\text{L}}^{\text{2}}}{{\text{T}}^{\text{-2}}}{{\text{A}}^{\text{-1}}}\text{ }\!\!]\!\!\text{ }\]

    Correct Answer: D

    Solution :

                    Magnetic flux = magnetic field \[\times \] area Dimensions of magnetic flux \[=\frac{F}{il}\times {{l}_{2}}=\frac{[ML{{T}^{-2}}]}{[L][A]}\times {{L}^{2}}\]                 \[{{\phi }_{B}}=[M{{L}^{2}}{{T}^{-2}}{{A}^{-1}}]\]
