Задача id10080

The frame through which the current passes rotates uniformly in a uniform magnetic field, the induction of which is 4 mT, with a frequency of 20 s-1. Frame area 20 cm2. The axis of rotation of the frame lies in its plane and is perpendicular to the field induction vector. Find the maximum magnetic flux through the plane of the frame and the induced emf that occurs in the frame when it rotates. Draw graphs of magnetic flux and induced emf versus time.
