Match List - I with List - II

Choose the most appropriate answer from the options given below:

Show answer and solution

Answer: (d)

Magnetic induction $B = \dfrac{F}{IL} = [\mathrm{MT^{-2}A^{-1}}]$ → (iii).
Flux $\phi = BA = [\mathrm{ML^2T^{-2}A^{-1}}]$ → (i).
Permeability $\mu = [\mathrm{MLT^{-2}A^{-2}}]$ → (iv).
Magnetization = magnetic moment per volume $= \dfrac{[\mathrm{L^2A}]}{[\mathrm{L^3}]} = [\mathrm{L^{-1}A}]$ → (ii).
So the answer is (d) (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii).
