Vedclass · Answer

(C) Magnetic intensity $(H)$ is defined as the magnetizing force per unit length.The formula for magnetic intensity is $H = \frac{nI}{L}$,where $n$ is the number of turns,$I$ is the current,and $L$ is the length.Since the number of turns $(n)$ is a dimensionless quantity,the dimensions of $H$ are given by the dimensions of $\frac{I}{L}$.The dimension of current $(I)$ is $[I^1]$ and the dimension of length $(L)$ is $[L^1]$.Therefore,the dimensions of magnetic intensity are $[L^{-1} M^0 T^0 I^1]$.
