A small circular loop of area A and resistance R is fixed on a horizontal xy-plane with the center of the loop always on the axis n-hat of a long solenoid. The solenoid has m turns per unit length and carries current I counterclockwise as shown. The magnetic field due to the solenoid is in the n-hat direction. List 1 give the dependence of n-hat in terms of a constant angular frequency omega. List 2 gives the torque experienced by the circular loop at time t=(pi)/[6(omega)], A is given.
