Question

The dimension of the magnetic field intensity $B$ is

• A. $M L T ^{-2} A ^{-1}$
• B. $M T^{-2} A^{-1}$
• C. $ML ^{2} TA ^{-2}$
• D. $M^{2} L T A^{-1}$

Answer 1

Answer: (B)

$F = BIL$
$B =\frac{ F }{ IL } \Rightarrow \frac{\left[ MLT ^{-2}\right]}{ A \times L }=\left[ MT ^{-2} A ^{-1}\right]$
