Решение задачи по физике раздел 56 пункт 29 электро

29. The flat circuit with a current I = 50 A is located in a homogeneous magnetic field (B = 0.6 T), so that a normal line perpendicular to the contour lines of the magnetic induction. Determine the work done by the field with a slow turning contour around an axis in the plane of the loop, at an angle of α = 30º.
