9. FALLING LOOP A rectangular loop is w in width and very long in height. It is held vertical, initially at rest. The loop has internal resistance R. It is in a region of space where there is a uniform magnetic field of strength Bo which is perpendicular to the plane of the loop. The region of space directly below the loop has no magnetic field in it. When the loop is dropped the magnetic flux will change and the...
