Question
Name the physical quantity whose unit is newton metre tesla ${ }^{-1}$ and whether is it scalar or vector?

Answer

$\tau_{\max }=m B \Rightarrow m=\frac{\tau_{\max }}{ B }$
On the basis of this formula, S.I. unit of M is newton metre tesla ${ }^{-1}$.
Hence, newton metre tesla ${ }^{-1}$ is S.I. unit of magnetic moment. It is a vector quantity.
