long circular tube of length 10 m and radius 0.3 m carries a current I along its
curved surface..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 = I0cos(300 t) where I0 is constant. If the magnetic moment of the loop is
Nm0I0sin(300 t), then ‘N’ is
