| 摘 要： | 文章通过麦克斯韦方程导出电磁辐射公式,在圆盘上任取一个带电小圆环,小圆环转动形成电流,电流产生电磁场,利用场强叠加原理得整个带电圆盘产生的电磁场,计算绕圆盘对称轴匀速转动产生的电磁场和转速周期性变化产生的磁感强度,并进行适当的讨论。

| Abstract: | This paper introduces the electromagnetic radiation formula through Maxwell's equation.Any charged small circle on the disk is taken,and electric current is formed by rotating them,and electromagnetic field is produced.The electromagnetic field of the whole charged disk is obtained by superposition principle of electric field,whose electric field strength is computed and discussed. |

| Keywords: | uniform rotation Maxwell's equation retarded potential electric field strength |
