A commutator on the coil shaft rectifies the induced sinusoidal current to pulsating direct current. Owing to parasitic voltages induced in the commutator by friction heating, the coil usually cannot be rotated in excess of 10 rps. The usual null detector is a tripod-mounted astatic galvanometer, with telescope and scale. To attain adequate sensitivity, instrumental vibrations must be minimized. In the field, a light breeze is sufficient to cause intolerable vibrations in the galvanometer suspension. It is therefore customary to set up the galvanometer and earth inductor tripods inside a tent. Alternating-current earth inductor. Some years ago Johnson [1936] pointed out that if an ac null detector and slip rings were substituted for the galvanometer and commutator the contact potentials could be ignored, thus permitting appreciably faster coil rotations.

An attempt was made to separate the electrojet ; contributions to the monthly mean of the daily range in H and Z. The jet appears ; to change its form with the season. The overhead disturbance currents appear ; north of Cebu at night, but south of Cebu during the day. Micropulsations, of ; peak-topeak amplitude of 1 gamma or greater, have a nonzero occurrence ; probability at any hour, with a maximum at local noon and a secondary maximum ; about midnight. The Johnston Island July 9, 1962, disturbance effects on the ; Philippine magnetic traces are presented. (auth);
