Induction coil sensors, also called search coils, pickup coils, or magnetic loop sensors, include variants such as Rogowski coils, gradiometers, vibrating coils, tangential field sensors, and needle probes. The review compares and summarizes design methods for air‑core and ferromagnetic‑core coils, analyzes their frequency properties, and presents various output signal‑processing techniques. The authors describe coil design methods, frequency‑response analysis, output‑signal processing techniques, and applications of coil sensors as magnetic antennas.
This review describes induction coil sensors, which are also known as search coils, pickup coils or magnetic loop sensors. The design methods for coils with air and ferromagnetic cores are compared and summarized. The frequency properties of coil sensors are analysed and various methods for output signal processing are presented. Special kinds of induction sensors, such as Rogowski coil, gradiometer sensors, vibrating coil sensors, tangential field sensors and needle probes are described. The applications of coil sensors as magnetic antennae are also presented.
