calculate the magnitude of the torque that the magnetic field exerts on the coil. Express your answer using two significant figures. The figure shows a rectangular coil of wire which carries a current of $I=10\mathrm{A}$ in the shown direction The coil is hinged along the $y$ axis and lies on an xy-plane. It is inside a uniform magnetic field $\vec{B}=(9\hat{i}?4\hat{k})$ T. If the dimensions of the rectangular are $a=10\mathrm{cm}$ and $b=4\mathrm{cm}$.
