electric flux, property of an electric field that may be thought of as the number of electric lines of force (or electric field lines) that intersect a given area. … Field lines directed into a closed surface are considered negative; those directed out of a closed surface are positive.

## What is a positive flux?

Flux is the rate of flow of the electric field through the given area. What is a positive flux? The flux is said to be positive when it leaves the closed surface. Flux depends on the surface size, the magnitude of the field and the angle between the surface and the magnetic field.

## What does it mean if electric flux is negative?

Electric Flux is defined as dot product between Electric field and area vector (We always take outward normal). Flux is negative implies that E and ds are anti-parallel. If net charge present inside that hypothetical surface is negative, then flux is negative.

## What do you mean by positive and negative magnetic flux?

Magnetic flux is a scalar quantity and its positive/negative sign indicates the direction of the magnetic field.

## How do you know if electric flux is positive or negative?

electric flux, property of an electric field that may be thought of as the number of electric lines of force (or electric field lines) that intersect a given area. Field lines directed into a closed surface are considered negative; those directed out of a closed surface are positive. …

## How do you know if flux is positive or negative?

Flux: The flow across a surface

- When the field vectors are going the same direction as the vectors normal to the surface, the flux is positive.
- When the field vectors are going the opposite direction as the vectors normal to the surface, the flux is negative.

## Is negative flux possible?

Yes, electric flux can be a negative number. When electric lines emerge out of surface, the electric flux is positive and when those lines enter into a surface, the electric flux in negative.

## Can flux be negative calculus?

Remember our convention for flux orientation: positive means flux is leaving, negative means flux is entering. In this example, water is falling downward, or entering the tube.

## Is outward flux negative?

Typically in this case we define “outward” flux to be positive, in which case the total electric flux through the surface will be a positive number since the electric field lines point out of a positively charged particle.
