Each of the coils should be placed with its axis perpen-dicular to that of the tube, so that the axes will cross in frontof the central diaphragm. The size of the wire used in the should be focused beforehand upon some well-defined object, suchas a lighted candle. In Figs. 2 and 3 are shown photographic reproductions of hys-teresis curves which were obtained in this way. The first curve is
