摘　　要：通过引入经典电磁学中运动电荷电磁现象,结合毕奥-萨伐尔定律,利用相对论变换关系讨论了不同参考系下电磁场量和电磁力.结果表明,经典电磁学可以有效解释运动电荷做低速运动时r电磁现象,推导过程和思路有利于加深对电磁现象的理解.By introducing the common teaching problems in the classical electromagnetics,combining the Biot-Savart law of moving charge and the electromagnetic field excited by moving charge,the quantity and force of electromagnetic field observed in different reference systems are discussed by using the relativistic transformation relationship,and the results show the electromagnetic phenomenon that charged particles move at low speed can be effectively explained by the classical electromagnetics.The derivation process and thinking are conducive to the understanding of electromagnetic phenomena in the teaching process.
