| 546. | The shock given by an electromagnet. | 180 |
| 547. | The apparent momentum The property of a moving body to continue in motion. of electricity. | 180 |
| 548. | The difference between this case and that of a tube containing a flow of water. | 181 |
| 549. | If momentum exists, it is not that of the moving electricity itself. | 181 |
| 550. | Nevertheless, the phenomena are exactly analogous to those of momentum. | 181 |
| 551. | An electric current possesses energy, which may be called electro-kinetic energy. | 182 |
| 552. | This leads us to develop a dynamical theory A theory based on the laws of force and motion. of electric currents. | 182 |
