Physics - Magnetism Question with Solution | TestHub

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