Quick Summary

An induction compass, also known as an inductor compass or earth inductor compass, is a navigational instrument that determines direction based on the Earth's magnetic field. Unlike a traditional magnetic compass, it operates by measuring the electric current generated in a coil as it rotates within the Earth's magnetic field. This principle is related to electromagnetic induction, where a changing magnetic field induces an electric current. The strength and direction of this induced current provide directional information, allowing the instrument to indicate north or south.1234

The gyromagnetic compass
…at both ends, or an inductor element can be employed. In one such arrangement, a saturable-inductor compass (so named because of its use of materials that can be readily induced to carry a maximum magnetic flow, or magnetic saturation) is mounted on a gyroscope, but this is not always convenient…
