\mathrm{ \begin{aligned} U_m & =-\vec{\mu}_s \cdot \vec{B} \\ \left|U_m\right| & =\mu_s B \end{aligned} Given, \begin{aligned} & \left|U_{\mathrm{m}}\right|=10^{-23} \mathrm{~J}, \mu_S \sim \mu_B=9.2 \times 10^{-24} \mathrm{Am}^2 \\ & =\sim 10^{-23} \mathrm{Am}^2 \\ & \therefore \quad B \sim \frac{10^{-23} \mathrm{~J}}{10^{-23} \mathrm{Am}^2} \\ & \sim \frac{10^{-23} \mathrm{Nm}}{10^{-23} \mathrm{Am}^2} \sim 1 \frac{\mathrm{N}}{\mathrm{Am}} \sim 1 \text { tesla. } \\ & \end{aligned} }
