SCM
Search Coil Magnetometer

A Search Coil Magnetometer (SCM) is a passive, remote magnetometer that detects lightning and rapid changes in the magnetic field. It operates on Faraday’s law of induction. When the magnetic field changes, it induces a current in the coil, which is then amplified and recorded. SCMs typically operate from 100 Hz to 100 kHz and are suitable for airborne, spaceborne, and ground-based applications.
