A conducting loop with area A sits in a uniform magnetic field of strength B, pointing out of the page, as shown. In time t, the direction of B is reversed so that it points into the page. a. What is the average EMF induced in the loop while the field is changing? b. Does the induced current flow clockwise or counterclockwise? B out of page Note: No quantitative calculations are necessary for this problem. You have a converging lens with focal length f. You place an object a distance o = f /4 in front of the lens. a. Sketch a ray diagram to demonstrate the location, orientation, and magnification of the image b. Based on your sketch, is the image: Real or virtual? Upright or inverted? Enlarged or reduced? 6.
