磁強計
Magnetometer
磁強計是測量磁感應強度的儀器。根據小磁針在磁場(chǎng)作用下能產(chǎn)生偏轉或振動(dòng)的原理制成。而從電磁感應定律可以推出，對于給定的電阻R的閉合回路來(lái)說(shuō)，只要測出流過(guò)此回路的電荷q，就可以知道此回路內磁通量的變化。這也就是磁強計的設計原理，用途之一是用來(lái)探測地磁場(chǎng)的變化。
Magnetometer is an instrument for measuring magnetic induction intensity. According to the principle that a small magnetic needle can deflect or vibrate under the action of a magnetic field. From the law of electromagnetic induction, it can be deduced that for a closed circuit with a given resistance R, the change of magnetic flux in the circuit can be known as long as the charge Q flowing through the circuit is measured. This is also the design principle of magnetometers. One of its uses is to detect changes in the geomagnetic field.
磁強計是用來(lái)測量磁感應強度的傳感器,在工業(yè)、農業(yè)、交通運輸、國防、航空航天、海洋、氣象、醫療衛生等領(lǐng)域均有廣泛應用。在地質(zhì)勘探領(lǐng)域,它可用于地磁場(chǎng)變化監測和地質(zhì)年代檢測;在醫療衛生領(lǐng)域,它常被用來(lái)檢測人體磁場(chǎng)并輔助疾病診斷;在國防上,它可以應用在磁性?huà)呃?、探測、磁波通訊、磁探針和磁導航;在外層空間探測中,它被用來(lái)進(jìn)行天體運行、演變的磁場(chǎng)檢測;而在衛星姿態(tài)測控中,可通過(guò)磁強計測量空間磁場(chǎng)來(lái)提供衛星姿態(tài)信息
Magnetometers are sensors used to measure magnetic induction intensity. They are widely used in industry, agriculture, transportation, national defense, aerospace, ocean, meteorology, medical and health and other fields. In the field of geological exploration, it can be used for geomagnetic field change monitoring and geological age detection. In the field of medical and health care, it is often used to detect human magnetic field and assist in disease diagnosis. In national defense, it can be used in magnetic mine clearance, bomb detection, magnetic wave communication, magnetic probe and magnetic navigation. In outer space exploration, it is used to detect the magnetic field of celestial bodies' movement and evolution. In satellite attitude measurement and control, magnetometers can be used to measure the space magnetic field to provide satellite attitude information.
