    A solenoid of length 0.4 m and having 500 turns of wire carries a current 3 A. A thin coil having 10 turns of wire and radius 0.1 m carries current 0.4 A. The torque required to hold the coil in the middle of the solenoid with its axis perpendicular to the axis of the solenoid is (μ0=4π×10−7\mu_0=4\pi\times10^{-7} SI units, π2=10\pi^2=10, sin⁡90∘=1\sin90^\circ=1)
