Abstract :
The characteristic of relative permeability and magnetic induction intensity of ferromagnetic material is the basis of the magnetic coupling sensor. And the detection and computing method of relative permeability is very important. In this paper, the relational model between magnetic induction intensity and relative permeability is researched. Its research productions, which have good theoretical significance and practical significance, lay the foundation for steel structure stress testing technology.
