The following information relates to questions 1-3. A single rectangular wire loop is located with its plane perpendicular to a uniform magnetic field of 2.0 mT. directed out of the page, as shown below. The loop is free to rotate about a horizontal axis XY. 3 cm X 21cm B out of page 1 How much magnetic flux is threading the loop in this position? 2 [ The loop is rotated about the axis XY, through an angle of 90, so that its plane becomes parallel to the magnetic field. How much flux is threading the loop in this new position? 3 If the loop completes one-quarter of a rotation in 40 ms, what is the average induced emf in the loop
