Question

Dimensions of magnetic field intensity is

• A. $\lbrack M^{0}L^{- 1}T^{0}A^{1}\rbrack$
• B. $\lbrack MLT^{- 1}A^{- 1}\rbrack$
• C. $\lbrack ML^{0}T^{- 2}A^{- 1}\rbrack$
• D. $\lbrack MLT^{- 2}A\rbrack$

Answer 1

Answer: (C)

$\lbrack ML^{0}T^{- 2}A^{- 1}\rbrack$

Answer 2

$B = \frac{F}{IL} = \frac{\lbrack MLT^{- 2}\rbrack}{\lbrack A\rbrack\lbrack L\rbrack} = \lbrack MT^{- 2}A^{- 1}\rbrack$
