# You asked: What is the orientation of the surface in an electric field to get maximum flux through it?

Contents

a. If the planar surface is perpendicular to the electric field vector, the maximum flux would be obtained. b. If the planar surface were parallel to the electric field vector, the minimum flux would be obtained.

## In which orientation is the electric flux through the surface equal to zero?

1: Flux of an electric field through a surface that makes different angles with respect to the electric field. In the leftmost panel, the surface is oriented such that the flux through it is maximal. In the rightmost panel, there are no field lines crossing the surface, so the flux through the surface is zero.

## What is the flux through the plane perpendicular to the field?

Answer: The magnetic flux through a unit area perpendicular to the field is Magnetic Flux Density. – It is defined as the amount of magnetic flux passing through per unit area of a section which is perpendicular to the direction of field.

## What is the electric flux through the Gaussian surface?

According to Gauss’s law, the flux of the electric field →E through any closed surface, also called a Gaussian surface, is equal to the net charge enclosed (qenc) divided by the permittivity of free space (ϵ0): … 4: The electric flux through any closed surface surrounding a point charge q is given by Gauss’s law.

## What is the electric flux through a circle?

Thus, the electric flux through the face of circle is 34.05N⋅m2/C 34.05 N ⋅ m 2 / C .

## What is the electric flux φ1 through surface 1?

The angle between the normal to the surface and the electric field lines is 180°. ϕ = E•s•cosθ = 400 × (2.0 × 4.0) × cos 180° = – 3200 V•m. A negative sign shows that flux is entering the surface. The flux through surface 1 is – 3200 V•m.

## How do you define electric flux linked with a surface?

Electric flux is the rate of flow of the electric field through a given area (see ). Electric flux is proportional to the number of electric field lines going through a virtual surface.

## When vector area is held perpendicular to the field lines then the magnitude of electric flux is?

Along the other four sides, the direction of the area vector is perpendicular to the direction of the electric field. Therefore, the scalar product of the electric field with the area vector is zero, giving zero flux.

## What is the use of introducing the ideas of magnetic flux and magnetic flux density?

Magnetic flux density is equal to the flux divided by the area. It is represents by B and its unit is tesla. Magnetic flux : The number of magnetic field lines passing through a closed surface.

## What is the magnetic flux density?

magnetic flux density. A vector quantity measuring the strength and direction of the magnetic field around a magnet or an electric current. Magnetic flux density is equal to magnetic field strength times the magnetic permeability in the region in which the field exists.

## How do you find the Gaussian surface?

3. Step 3: Check the area vector (A) …
4. Step 4: Check the angle between area vector (A) and electric field (E)

## What is the electric flux through the Gaussian surface containing two electric dipoles?

Now, the total charge enclosed by our Gaussian surface is zero, so according the Gauss’ Law the flux through the Gaussian surface is zero, and so is the electric field intensity due the electric dipole.

## How is electric flux defined in an electric field through an arbitrary Gaussian surface?

According to Gauss’s law, the flux of the electric field through any closed surface, also called a Gaussian surface, is equal to the net charge enclosed divided by the permittivity of free space : This equation holds for charges of either sign, because we define the area vector of a closed surface to point outward.

## When electric flux is maximum?

The electric flux of a surface is maximum when the area vector is parallel to the direction of the electric field. The electric flux is the total number of lines of force passing through a surface. Electric flux is proportional to the number of electric field lines going through a virtual surface.
