During the measurement we found it鈥瞫 difficult to place the equipment underwater, so it鈥瞫 unpractical to measure the electromagnetic component at arbitrary position in the sea. By analyzing its theory of transmission, this paper presents a rapid estimation method of power frequency magnetic field, and validates its validity by experimentation.
