Earth's Magnetic Field

An account is given of a simple experiment designed to illustrate quantitatively the phenomena of coupled oscillations. Two similar small magnets are suspended in the earth's magnetic field at a suitable distance apart so that there is appreciable magnetic interaction between the two oscillatory systems. Under the conditions employed, the equations of motion reduce to a simple form, and the experiment may be used as a method of measuring the intensity of the horizontal component of the earth's magnetic field.

Comparison Of The Results

The discrepancies found by Professor Rücker and the author to exist between the values for the horizontal component of the earth’s magnetic field, as measured by the absolute instruments in use in the various British observatories, were so great that it seemed of interest to measure the field at one of the observatories by an entirely different method, in order, if possible, to obtain some indication as to the reliability of the various instruments. Further, in the ordinary method of measuring H, a correction has to be applied on account of the distribution of the magnetism in the magnets employed, about the value of which there is some uncertainty.

Comparison Of The Results

A comparison of the readings given by the magnetometers used for measuring the horizontal component of the earth’s magnetic field at the various observatories in Great Britain having shown the existence of very marked discrepancies, although the instruments employed are all of the same type, it seemed of interest to employ some entirely different method for the measurement of H, and to compare the results with those given by the unifilar magnetometers.

Earth's Magnetic Field

The measurement of the vertical component of the earth’s magnetic field is a less simple operation than that of the horizontal component. The horizontal field measurements are on a satisfactory basis, whether made by the swinging magnet method, or by the more recently developed electric magnetometers, in which known magnetic fields may be provided by means of known currents flowing through coils of known dimensions.
