补充资料:电磁力
电磁力 electromagnetic force 电荷、电流在电磁场中所受力的总称。也有称载流导体在磁场中受的力为电磁力,而称静止电荷在静电场中受的力为静电力。电工中所关注的电介质在电磁场中受到的有质动力也是电磁力。电机中起主要作用的力通常是磁场作用在铁质电枢上的有质动力,而不是载流导体上受的力。电枢上受的有质动力可以运用虚位移方法由外源供能、场能、机械功的平衡式导出。今在一定技术条件下,可以产生强磁场和大电流,从而获得强大的磁力,但却难以获得大量的静电荷和强电场以产生强大的静电力。几乎所有的电动机都靠磁力驱动。一些静电仪器、电子管器件、静电除尘装置等,以静电力实现其功能。 |
