A small rectangular coil of 6 mm by 6 mm is placed in the middle of a solenoid of 40 mm length having 100 turns and carrying a current of 3 A. The sides of the coil are perpendicular to the magnetic field lines of the solenoid. Calculate the force on each side of the rectangular coil due to the magnetic field of the solenoid given that a current of 2.0 A is passed through the small coil. Take vacuum permeability D4xx 10 H/m. Provide your answer in units of micro Newtons (uN, 10 N). %3!
