The correct answer is:
Am
Dipole moment of a magnet,
\(\begin{array}{ll}
\Rightarrow & M=I A \\
\Rightarrow & 2 m l=I A \quad[m=\text { pole strength] }
\end{array}\)
\(\begin{aligned}
\text {Unit of pole strength } (m) & =\frac{\text { Ampere } \times \text { metre }^2}{\text { metre }} \\
= & \frac{\mathrm{Am}^2}{\mathrm{~m}}=\mathrm{Am}
\end{aligned}\)
\(\begin{array}{ll}
\Rightarrow & M=I A \\
\Rightarrow & 2 m l=I A \quad[m=\text { pole strength] }
\end{array}\)
\(\begin{aligned}
\text {Unit of pole strength } (m) & =\frac{\text { Ampere } \times \text { metre }^2}{\text { metre }} \\
= & \frac{\mathrm{Am}^2}{\mathrm{~m}}=\mathrm{Am}
\end{aligned}\)
