    A long circular tube of length $10 \ m$ and radius $0.3 \ m$ carries a current $I$ along its curved surface as shown. A wire-loop of resistance $0.005$ ohm and of radius $0.1 \ m$ is placed inside the tube with its axis coinciding with the axis of the tube. The current varies as $I=I_0 \cos (300 t)$ where $I_0$ is constant. If the magnetic moment of the loop is $N \mu_0 I_0 \sin (300 t)$, then ' $N$ ' is
