Solving a problem in physics section 1 paragraph 49 ele

49. A short coil comprising turns N = 103 uniformly rotates at n = 10 c-1 with respect to the axis AB, in the plane of the coil and perpendicular to the lines of the homogeneous magnetic field (B = 0,04 T). Determine the instantaneous value of the induction EMF for those times when the plane of the coil makes an angle α = 60° lines field. The area of the coil is equal to S = 100 cm2.
