Physics - Magnetism Question with Solution | TestHub

A rectangular coil (Dimension$5\mathrm{ }\mathrm{c}\mathrm{m}\mathrm{ }\times \mathrm{ }2.5\mathrm{ }\mathrm{c}\mathrm{m}$) with$100$turns, carrying a current of$\mathrm{ }3\mathrm{ }\mathrm{A}$in the clock-wise direction, is kept centered at the origin and in the$\mathrm{X}-\mathrm{Z}$plane. A magnetic field of$1\mathrm{ }\mathrm{T}$is applied along$\mathrm{X}-\mathrm{a}\mathrm{x}\mathrm{i}\mathrm{s}$. If the coil is tilted through$45°$about$\mathrm{Z}-\mathrm{a}\mathrm{x}\mathrm{i}\mathrm{s}$, then the torque on the coil is:
