A) \[[ML{{T}^{-1}}{{A}^{-1}}]\]
B) \[[M{{L}^{-1}}T{{A}^{-2}}]\]
C) \[[M{{L}^{-2}}{{T}^{2}}{{A}^{-2}}]\]
D) \[[M{{L}^{2}}{{T}^{-2}}{{A}^{-1}}]\]
Correct Answer: D
Solution :
Magnetic flux \[(\phi )=\] (Magnetic field) \[\times \] (Area) or \[[\phi ]=[B][A]\] \[=\frac{[Force][Area]}{[Current][Length]}=\frac{[ML{{T}^{-2}}][{{L}^{2}}]}{[A][L]}\] \[|\phi |=[M{{L}^{2}}{{T}^{-2}}{{A}^{-1}}]\]
