In a homogeneous magnetic field with induction B = 0.1T, a frame containing N = 1000 turns of wire rotates uniformly with a frequency of n = 10 r / s. The axis of the frame is perpendicular to the direction of the magnetic field. The area of the frame is S = 150 cm2. Find the instantaneous EMF induction value corresponding to the rotation angle of the frame of 30 degrees.
