What is electric lines of force in physics?

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.

NEED TO KNOW:  What electric truck can I buy now?

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 .
