This paper makes a further analysis of the traditional opinion about Ampere force that is the macroscopic showing of Lorentz force,and it demonstrates that microscopic nature of Ampere force is composition of electric field forces applied by Hall electric field which is caused by Lorentz forces for the positive ions at the crystal lattice of the conductor in magnetic field.

Firstly, according to electromagnetic field theory, the 2-dimensional (2-D) mathematical model of a three phase squirrel-cage Y802-2 induction motor is developed. Then general equations can be deduced from finite element discrete and functional analysis. The motor's 2D solving region of electromagnetic field is given based on the boundary conditions and assumption conditions of the squirrel-cage induction motor. Through finite element mothod and inner–outer convergence method, magnetic field distributions and magnetic forces of bars can be calculated in following rotor conditions: health rotor, one single broken bar, two adjacent broken bars, two broken bars with one good interval, two broken bars with two good interval and four adjacent broken bars.
