A 2A current carrying straight metal wire of resistance $\displaystyle 1 \Omega$, resistivity $\displaystyle 2 \times 10^{-6} \Omega \mathrm{~m}$, area of cross-section $\displaystyle 10 \mathrm{~mm}^2$ and mass $\displaystyle 500$ g is suspended horizontally in mid air by applying a uniform magnetic field $\displaystyle \vec{B}$. The magnitude of $\displaystyle B$ is $\displaystyle \_\_\_\_$ $\displaystyle \times 10^{-1} \mathrm{~T}$ (given, $\displaystyle g=10 \mathrm{~m} / \mathrm{s}^2$ ).
