通过对一铁磁性试件进行磁记忆检测实验,选择手机信号作为干扰源,研究不同环境磁场下试件磁记忆检测信号的变化情况.同时,对试验过程中的环境磁场对磁场强度变化的影响进行了机理分析.研究结果表明：对不同程度的环境磁场干扰,检测得到的试件磁记忆信号差别显著;周围有放置手机但不通话时,环境磁场的干扰程度不大;随着周围环境的通话手机数量逐渐增多,环境磁场的干扰程度不断加大直至足以影响检测精度.

Through the metal magnetic memory testing experiment of a ferromagnetic material,the magnetic signal changes of specimens in different environment magnetic fields were studied by choosing the mobile signal as the disturbance sources.The results indicate that the magnetic signals of specimens have obvious difference in different environment magnetic fields.The disturbance of the environment magnetic field is weak while a mobile phone is placed around but without calling.With the increase of the mobile calling,the disturbance degree continuously increases until it is strong enough to affect the test accuracy.
