Abstract
A saturable-core magnetometer for measuring magnetic fields of the order of a fraction of 1 ma (milli-ampere) turn per cm (centimeter) is suggested. Its operation is based on a saturable-core element, wherein position-modulated voltage pulses are induced, their shift being linearly related to H0, the field under investigation. By means of a simple analyzer, information about the unknown field contained in the position-modulated pulses is translated into a d-c voltmeter indication. Linearity, sensitivity, and zero-drift ¿ as influenced by parameter variation and temperature changes ¿ are examined. Agreement is checked between experimental results and those anticipated from theory.
