| Abstract: | The theory of operation of geomagnetic induction coil is introduced in this paper.For meeting the requirements of measuring the rotation of expendable probes,a special coil and measuring circuit are designed,and a special test-bed is set up for experiments in lab for measuring the rotation of expendable probes.Results of experiments show that exact data about the velocity of the probe rotation can be obtained with the geomagnetic induction coil,and it is indicated that the device can be employed for determining the underwater rotation of expendable probes. |
