对称激变磁场相互作用及其特性研究

Interaction of the Symmetric Excitation Magnetic and Its Character Research

摘要: 在漏磁检测磁化实验中发现同向强磁场相互作用会产生一种新的物理现象——激磁脉冲波现象。激磁脉冲波是一种同极性磁场相互作用，在相互作用过程中，极大的磁场梯度使磁场能向磁场梯度小的区域移动传播而形成的磁性脉冲波。本文深入研究了激磁脉冲波现象的物理本质，并将其描述为两个同极性磁场的撞击过程。在此基础上，设计了有效的激发和接收装置，并对激磁脉冲波的波速、介质中的传播特性和感生电磁波的特性进行了实验研究。结果表明激磁脉冲波非常适宜应用于信息通讯和目标探测，因此，进一步研究激磁脉冲波具有非常重要的意义。

Abstract: The phenomenon of Excitation Magnetic Impulse Wave (EMIW) is a new physical phenomenon discovered in the procedure of the magnetization of the Magnetic Flux leakage Test. In this paper a pilot study is carried out to explore the physical essence of the phenomenon, which can be described as the impact of two homopolar magnetic fields. Moreover, effective excitation and receiving device are successfully designed in experiments, and we realize the primary analyses and study on its velocity, the characteristic of the induced electromagnetic and propagation characteristic in medium. The results show that EMIW is extremely suitable to apply to the fields of information communication and object detection, so it is most essential to spend more time on the EMIW research.
