MCQ
Dimensions of magnetic field intensity is
  • A
    $\left[M^0 L^{-1} T^0 A^1\right]$
  • B
    $\left[M L T^{-1} A^{-1}\right]$
  • ✓
    $\left[M L^0 T^{-2} A^{-1}\right]$
  • D
    $\left[M L T^{-2} A\right]$
✓

Answer

Correct option: C.
$\left[M L^0 T^{-2} A^{-1}\right]$
(c) $B=\frac{F}{I L}=\frac{\left[M L T^{-2}\right]}{[A][L]}=\left[M T^{-2} A^{-1}\right]$
