magnetic field
The article studies the change in the statistical properties of measurements of the Z-component of the Earth’s magnetic field, carried out on mutually distant magnetometers during 15 days before the earthquake of February 6, 2023 in eastern Turkey. The differences in the corresponding statistics associated with both the difference in directions to the epicenter and the significant difference in distances to azimuthally close magnetometers are analyzed.

We conducted an undersea magnetic induction (MI) communication experiment in the South China Sea to demonstrate the feasibility of a rotating permanent magnet transmitter. The rotating permanent magnet transmitter is placed on the floating platform for generating the inductive magnetic field, and a ferrite-rod coil with the glue-filled waterproof seal is hung in the seawater as a receiving antenna. This data is a received magnetic signal at a depth of 30 m in seawater.

The EKF-based dynamic magnetic field calibration algorithm uses gyroscope data to calibrate magnetic field data. The magnetic field data can be well calibrated to the surface of the magnetic field sphere, which is superior to the traditional ellipsoid fitting algorithm.
