These two reports were issued separately, but are cataloged as a unit. A method is described to measure dynamic magnctic fields and field gradients to a high accuracy in a strong focusing synchrotron. It employs comparative techniques, peaking strips for timing and an electronic integrator. The method is sensitive down to fields of about 100 gauss. The absolute n-value (field gradient divided by field- is measured to 0.25%, whereas a relative n- distribution over a magnet can be measured to 0.1%. Data are given for CEA magnet Model Mark II between 100 and 4000 gauss, including influence of a vacuum chamber model. The fact that the magnet ends present a sloping n-face is demonstrated. With a more sensitive pair of gradient search coils, the orbit nvalue in the center of a magnet is investigated down to 25 gauss. (auth)
