摘要
讨论有电磁感应时,载流导线在磁场中的运动规律及磁力对载流导线所作的功。并说明磁力作功的能量来源是电源为克服感应电动势而额外供出的能量。
The moving law of a current-carrying wire in magnetic field and the work done by magnetic force for it are discussed. It is showod that the needed energy of doing work comes from the pawer source,i. e., to overcome the induced potential the power source must supply extra energy.
