Abstract: According to the law of electromagnetic induction and the characteristics of current magnetic field of solenoid,a finite element model of the magnetic field on the surface or the interior of long straight solenoid was established.By means of theoretical deduction and numerical analysis based on the law of biot savart and Ampere circuital theorem of magnetic field in a straight solenoid,the characteristics of distribution of magnetic field and its analytical solution were obtained.The simulation was carried out on using of Ansoft Maxwell 3D engineering electromagnetic field finite element software,the consistency of the result and the intuitive and convenient of using ANSYS software for electromagnetic field analysis were verified. -
