A circular loop with a radius of 0.21 m is rotated by 90.0° over 0.210 s in a uniform magnetic field with B = 1.40 T. The plane of the loop is initially perpendicular to the field and is parallel to the field after the rotation. (a) What is the average induced emf in the loop? V (b) If the rotation is then reversed, what is the average induced emf in the loop? V
