Q. The dimension of the magnetic field intensity $B$ is
A) $MLT^{- 2}A^{- 1}$
B) $MT^{- 2}A^{- 1}$
C) $ML^{2}TA^{- 2}$
D) $M^{2}LT^{- 2}A^{- 1}$
Explanation
(b) $F = Bil \Rightarrow \lbrack B\rbrack = \frac{\lbrack F\rbrack}{\lbrack i\rbrack\lbrack l\rbrack} = \frac{MLT^{- 2}}{AL} = MT^{- 2}A^{- 1}$
