Vedclass · Answer

(A) The expression $\frac{B^{2}}{2 \mu_{0}}$ represents the magnetic energy density,which is the magnetic energy stored per unit volume.The formula for energy density is $u = \frac{	ext{Energy}}{	ext{Volume}}$.The dimension of energy is $[M L^{2} T^{-2}]$ and the dimension of volume is $[L^{3}]$.Therefore,the dimension of energy density is $\frac{[M L^{2} T^{-2}]}{[L^{3}]} = [M L^{-1} T^{-2}]$.Thus,the dimension of $\frac{B^{2}}{2 \mu_{0}}$ is $[M L^{-1} T^{-2}]$.
