Задача 30523.

Determine the magnetic moment of a galvanometer coil consisting of 400 turns of wire wound on a rectangular frame with a cross section of 4 cm ^ 2 at a current of 10 ^ -7 A. What torque acts on the coil in a uniform magnetic field with an induction of 0.1 T, if the plane of the coil is 60 ° with the direction of the magnetic field.
