electrical line of force
- noun
- Specialized
- The electrical line of force indicates the direction of the electric field.
Examples
-
Diagrams often illustrate the direction of an electric field with curved electrical lines of force.
-
When you place a conductor in the field, the electrical lines of force become distorted around it.
-
The pattern of electrical lines of force between two charges reveals the nature of their interaction.
-
In physics, an electrical line of force helps visualize electric fields.

Synonyms
An imaginary line that shows the direction of the force around magnets or electric charges
An imaginary line that shows the direction of force at points in an electric or magnetic field

Morphology
electrical + line + of + force
The phrase is fully compositional: 'electrical' modifies 'line of force', so a learner who knows 'electrical', 'line' and 'force' can infer it refers to a (conceptual) line showing electrical force. This is a standard noun phrase pattern and the idea of a line indicating direction/strength of a force is cross-linguistically transparent, so a B1 learner should be able to derive the meaning from the constituents.
Etymology
Electrical line of force comes from the idea of drawing an electrical line to show how the electric force would push a small positive charge along a path. So the phrase means an 'imaginary line' that shows the 'direction and strength' of an electric field.
