摘要
由于微弱的杂散磁场对飞机的导航系统和控制信号均有干扰,国际航空运输守则(International Air Transport Association简称IATA)将磁性货物列为第9类危险品,在收运时加以限制。该文重点阐述一种适用于对空运货物进行杂散磁场检测的磁检仪的设计。
As weak magnetic field has interference on the guiding system and electrical signal of the aircraft, IATA classifies magnetized material as Class 9 dangerous goods. There are some regulations for magnetized material during air transportation. In this paper, we specifically design a magnetometer to test the magnetic field of the cargo for airfreight.
