The dimensional formula of magnetic induction $B$ is

• A

  [${\mathrm{M}}^0\mathrm{A}\mathrm{L}{\mathrm{T}}^0$]
• B

  [${\mathrm{M}}^0\mathrm{A}{\mathrm{L}}^{-1}{\mathrm{T}}^0$]
• C

  [${\mathrm{M}}^0\mathrm{A}{\mathrm{L}}^2{\mathrm{T}}^0$]
• Correct answer
  D

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

Hence, the correct answer is option: 'D'.
