A magnetized bullet flies along the axis of a thin flat coil connected to a ballistic galvanometer through an ideal rectifying element. The bullet is magnetized along its axis, its dimensions are small compared to the diameter of the coil D. Determine the magnetic moment of the bullet m if it is known that the galvanometer deviated after the bullet flew by an angle j. The ballistic constant of the galvanometer b [rad/C], the number of turns of the coil n and the circuit resistance R are known.
