A galvanometer coil has $\displaystyle 500$ turns and each turn has an average area of $\displaystyle 3 \times 10^{-4} \mathrm{~m}^2$. If a torque of $\displaystyle 1.5$ Nm is required to keep this coil parallel to a magnetic field when a current of $\displaystyle 0.5$ A is flowing through it, the strength of the field (in T ) is \_\_\_\_.
