A solenoid has 1000 turns per meter and carries a current of \( \frac{7}{\pi} \) A. The magnetic field inside the solenoid is
Show Hint
Be careful to distinguish between total turns '$N$' and turns per unit length '$n$'. The formula uses $n = N/L$. The problem directly gives '$n$' (1000 turns per meter).

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