Question:

The dimension of magnetic induction can be written as

Options:

$[M^1L^0T^{-2}A^{-1}]$

$[M^1L^2T^{-2}A^{-1}]$

$[M^1L^1T^{-2}A^{-1}]$

$[M^1L^0T^{-2}A^1]$

Correct Answer:

$[M^1L^0T^{-2}A^{-1}]$

Explanation:

The correct answer is Option (1) → $[M^1L^0T^{-2}A^{-1}]$

Magnetic field, $B=\frac{F}{qV}$

$=\frac{[M^1L^1T^{-2}]}{[A^1T^1][L^{+1}T^{-1}]}$

$= [M^1L^0T^{-2}A^{-1}]$
