| 4. | This is not entirely frivolous; a strong magnetic field, for instance, can constrain electrons to move only along the field lines .
这不是完全无价值的，例如，强磁场可约束电子使之只能沿着场力线运动。 |
| 5. | Now suppose that for some reason, a depression or hollow develops in a system of field lines stretching "horizontally" .
