Paperback. Condición: New. Print on Demand. This book examines the investigation of the eleven (or ten) year period and the disturbances of the vertical force. The author presents a detailed analysis of data collected from observations of the vertical component of the magnetic force ranging from 1840 to 1845, using various instruments, including a balance vertical force magnetometer and a reecting vertical force magnetometer. The book includes an examination of the temperature coefcient of the instruments used and a discussion of the results obtained. The author also explores the diurnal and annual inequality in the number and magnitude of the disturbances of the vertical force, and discusses the effect of the aurora borealis on the declination, and the horizontal and vertical force as observed at the Girard College Observatory. This book provides valuable insights into the study of terrestrial magnetism and the effects of auroral displays on the Earth's magnetic field.
