The electric lines of force that represent the field of a positive electric charge in space consist of a family of straight lines radiating uniformly in all directions from the charge where they originate. … An electric charge traveling along a magnetic field line undergoes no magnetic force.

## What is an electric line of force?

An electric line of force is **an imaginary curve drawn in such a way that tangent to this curve at any point gives the direction of the electric field at that point**. It can be a path with maybe a curve or a straight line. … Electric lines of forces start from a positive charge and end in negative charge.

## What is electric lines of force and its properties?

Properties of Electric Field Lines

The field lines never intersect each other. Electric lines of force contract longitudinally. **They expand laterally**. The magnitude of charge and the number of field lines, both are proportional to each other.

## What are lines of force and what force is it?

: a line in a field of force (such as a magnetic or electric field) **whose tangent at any point gives the direction of the field at that point**.

## What are lines of force in art?

A force line represents **graphically the internal force acting within a body across imaginary internal surfaces**. The force lines show the maximal internal forces and their directions.

## What is a line of work?

: **the work that a person does regularly in order to earn money** : job He’s in a dangerous line of work.

## What are the rules concerning the lines of force?

The electric lines of force that represent the field of a positive electric charge in space consist of **a family of straight lines radiating uniformly in all directions from the charge where they originate**. A second positive charge placed in the field would travel radially away from the first charge.

## Why is a line of force so named?

**The direction of force is along the tangent for a positive magnetic charge (north pole) and opposite for a negative magnetic charge (south pole)**. This explains why the alternate term for field lines “lines of force” is named in that way.

## Are flux lines real?

**There are no “real” lines of force**. Fields lines are simply a mathematical construct used for visualization only. Only the allignment, i.e. direction, of the filings are measurable.

## What do you call the total number of electric lines of force in an electric field?

**Electric flux** is a measure of number of field lines passing through a surface and is given by. ϕ=E .
