Task 31043.

As long solenoid with a density of turns 20 cm ^ -1 flowing current I1 = 0,5 A. Inside the coil is a square loop of 10 turns. Side loop 3 cm. The magnetic moment of the loop of 2.7 x 10 -3 A * m ^ 2. The plane makes an angle of 30 ° with the magnetic field lines of the solenoid. Determine: current strength I2 in the circuit; the torque acting on the circuit; the work done at the turn of the circuit in a position where the magnetic flux is greatest.
