# A uniform magnetic field of $3000\;G$ is established along the positive z- direction . A rectangular loop of sides $10\;cm$ and $5\;cm$carries a current of $12\;A$. What is the torque on the loop in the fig? What is the force ?
$\begin{array}{1 1} \text{$T=-1.80 \times 10^{-2} \hat j N-m$, along negative y- direction } \\ \text{$T=1.80 \times 10^{-2} \hat j N-m,$along positive y- direction } \\ \text{$T=-1.80 \times 10^{-2} \hat j N-m,$along negative z- direction } \\ \text{$T=-2.80 \times 10^{-2} \hat j N-m,$along negative y- direction } \end{array}$
