Making of the simulation system for the force of the current-carrying circular coil in non-uniform magnetic field

For the current-carrying circular coil in non-uniform magnetic field, its force was shown as three-dimension effect with two-dimension plane. A new method had been put forwarded. First of all, the three-dimension model had been built. The second stage was based on the methods of limit analysis and vector analysis. The method of limit analysis was suit for getting the angle between the direction of the current element in the current-carrying circular coil and the direction of its magnetic induction. The method of vector analysis was suit for obtaining the angle between the direction of the force of the current element and horizontal plane. The force was Ampere force and it was calculated by Ampere´s law. The component of the force in the horizontal plane had been calculated. The finally stage was very important stage. In the stage, the simulation system had been developed by Multimedia ToolBook. In the system, the relative size and the direction of the force for the current element could be shown as three-dimension effect at once when the mouse entered into the current element. The users could drag the current-carrying straight wire in horizontal direction. The coordinate values in the central position of the current-carrying circular coil and the radius of the coil could be changed by users. The simulation system had good effect and the high degree of intelligence.
