Abstract

The invention discloses a device for measuring a terrestrial magnetism horizontal component, comprising a coil, a suspension device, and a torsion amplification device. The coil is suspended in the air through the suspension device and is twisted under the action of the terrestrial magnetism after being electrified; the torsion amplification device performs display amplification on the torsion angle of the coil; and the terrestrial magnetism horizontal component can be obtained through measuring the result after display amplification. The device for measuring the terrestrial magnetism horizontal component utilizes the mechanics and the optics principle, can accurately measure the magnitude of the geomagnetic field and is simple in operation and low in cost.

Description

technical field [0001] The invention relates to a measuring device, in particular to a device for measuring geomagnetic horizontal components, and belongs to the field of physical detection instruments. Background technique [0002] At present, there are not many devices for measuring the horizontal component of geomagnetism. Gao Jiandong and others use devices made of spherical and square bias coils to measure the horizontal component of geomagnetism, but the devices are difficult to manufacture, complicated and costly. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a device for measuring the horizontal component of geomagnetism, so as to solve the technical problems of difficulty in making the device in the prior art, relatively complicated and high cost. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A devic...
