| Abstract: | For magnetic field generated by a current along any curve, the calculation equations are written based on Biot-Savart law and the superposition principle. The 3-M softwares are employed to compute and plot on PC. Taking solenoid carrying current as an example, the program is made to compute and illustrate the distribution of magnetic field inside and outside the solenoid. Thus the field is analyzed qualitatively and quantitatively. |
