Problems solved by technology
[0002] The south and north magnetic poles of the earth do not overlap with the rotation axis of the earth, indicating that the movement of the magnetic source that excites the earth's magnetic field inside the earth is not consistent with the rotation of the earth, but because the magnetic source that excites the earth's magnetic field is located in the deep Near the junction between the core and the mantle, people cannot directly observe the motion of the material that excites the Earth's magnetic field. They can only infer the motion state of the material that excites the Earth's magnetic field at a depth of thousands of kilometers inside the Earth by measuring the motion speed of the geomagnetic field lines on the Earth's surface. , therefore, if the movement speed of the geomagnetic field lines can be measured at different locations around the world, it will help to deepen human understanding of the movement state of the magnetic source that excites the earth's magnetic field inside the earth

The instrument comprises the electromagnetic annular winding installed on the seat mode from non-magnetic material. The magnetic shielding cover made of magnetic material is setup on a part of annular external surface of said electromagnetic winding. The two ends of the electromagnetic winding through conducting wires are connected to the voltmeter. The electromotive force generated by the moving magnetic line of the geomagnetism to cut the electromagnetic winding can be measured by the voltmeter. Based on the formula V=U / NBL, where B as the magnetic induction of the geomagnetic field at the measuring place, L as the length of the magnetic shielding cover, N as number of turns of the winding. Thus, V as the moving speed of geomagnetic field can be obtained.
Description
technical field [0001] The invention relates to a measuring instrument for measuring the moving speed of the geomagnetic magnetic force line which can measure the moving speed of the geomagnetic magnetic force line.
