Compared with ordinary concrete, its performance is greatly improved, and it is widely used in industrial workshop floor, highway pavement, military antiknock engineering enhanced concrete structure. But chaos to distribution in steel fiber reinforced concrete steel fiber makes the material not be able to give full play to its advantages. Sometimes we need to make steel fiber on the directional arrangement according to the engineering requirement. Steel fiber as ferromagnetic material will be along the lines of magnetic force deflection under the action of electromagnetic field. We will directional steel fiber through the design of adjustable electromagnetic fields. Firstly electric solenoid generates specific magnetic field, and then using MATLAB software to numerically calculate designed magnetic field. And then draw the lines of magnetic force vector diagram, verify the feasibility of magnetic field, and analyze the solenoid related parameters such as length, radius and spacing on the influence of the magnetic field distribution. Satisfied parameter values of the preparation of directional magnetic field will be obtained.
