| Abstract: | 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. |

| Keywords: | induced potential induced eurrent ampere force |
