magnetometer   (māg'nĭ-tŏm'ĭ-tər)  Pronunciation Key 
An instrument for measuring the magnitude and direction of a magnetic field. Magnetometers are often used in archaeological and geological investigations to determine the intensity and direction of the Earth's magnetic field at various times in the past by examining the strength and direction of magnetization of ferromagnetic materials in different geological strata. See also magnetic reversal.
