Electromagnetic Speed Log Transducer The electromagnetic sensor houses a coil which, when energised with an AC current, produces a magnetic field around the sensor in the surrounding water. The ship’s motion through the water produces an electrical field perpendicular to the magnetic field and the ship’s motion. The resulting signal is picked up by the sensor electrodes and fed to the preamplifier, where it is converted into a digital format and transmitted to the master unit.
