In a uniform magnetic field of \(0.049 \mathrm{~T}\), a magnetic needle performs 20 complete oscillations in 5 seconds as shown. The moment of inertia of the needle is \(9.8 \times 10^{-6} \mathrm{~kg} \mathrm{~m}^2\). If the magnitude of magnetic moment of the needle is \(x \times 10^{-5} \mathrm{~Am}^2\), then the value of '\(x\)' is :
