    Dimensions of magnetic field intensity is                     [RPMT 1997; EAMCET (Med.) 2000; MP PET 2003]

    A)             \[[{{M}^{0}}{{L}^{-1}}{{T}^{0}}{{A}^{1}}]\]      

    B)             \[[ML{{T}^{-1}}{{A}^{-1}}]\]

    C)             \[[M{{L}^{0}}{{T}^{-2}}{{A}^{-1}}]\]

    D)             \[[ML{{T}^{-2}}A]\]

    Correct Answer: C

    Solution :

                    \[B=\frac{F}{IL}=\frac{[ML{{T}^{-2}}]}{[A]\,[L]}=[M{{T}^{-2}}{{A}^{-1}}]\]
