# You asked: Under what condition electric flux will be maximum or minimum through a closed surface?

Contents

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.

## Under what conditions can the electric flux be found through A closed surface?

Only if the location of each point charge inside the surface is specified.

## When the magnetic flux is minimum and maximum?

Equation (2) shows that the magnetic flux is maximum when the angle between a magnetic field and normal to an area is zero. If the magnetic field is parallel to the plane of area and angle between the field and normal to an area is 90° as shown in the figure.

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

The net flux through a closed surface is a quantitative measure of the net charge inside a closed surface. 2. The net electric flux through any closed surface surrounding a net charge ‘q’ is independent of the shape of the surface. … The net electric flux is zero through any closed surface surrounding a zero net charge.

## When magnetic flux is maximum?

Magnetic flux through a coil is maximum when it is equal to zero. Thus, equate this equation to zero and find the angle between the plane of the coil and lines of force.

## Under what conditions it is concluded that the net electric flux through a closed surface is zero?

The total charge inside the surface must be zero.

## What is the necessary and sufficient condition for the electric flux through a closed surface to be zero?

the charge inside the surface must be zero.

## Under which condition the flux is minimum?

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

## In what condition will the magnetic flux through a surface of a fixed area be at its maximum value?

If the surface is perpendicular to the field (left panel), and the field vector is thus parallel to the vector, →A, then the flux through that surface is maximal. If the surface is parallel to the field (right panel), then no field lines cross that surface, and the flux through that surface is zero.

## How do you find the maximum magnetic flux?

In the most general form, magnetic flux is defined as ΦB=∬AB⋅dA Φ B = ∬ A B ⋅ d A . It is the integral (sum) of all of the magnetic field passing through infinitesimal area elements dA.

## Under what conditions is the net electric flux through a closed surface proportional to the enclosed charge?

The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero. If a net charge is contained inside a closed surface, the total flux through the surface is proportional to the enclosed charge, positive if it is positive, negative if it is negative.

## What will be the electric flux through a closed surface if its size is doubled?

d→S=qε0 ϕE∝∫dS ∴ Flux will also doubled, ie, 2ϕ .

## What is the amount of electric flux through a closed surface due to an electric dipole?

Brainly User. 0(zero) because dipole has equal and opposite charge so net charge is zero and flux is also zero.

## Why the magnetic flux on a closed surface is zero?

Because magnetic field lines are continuous loops, all closed surfaces have as many magnetic field lines going in as coming out. Hence, the net magnetic flux through a closed surface is zero.

## When the magnetic flux is maximum the induced emf is also maximum?

By Faraday’s law, the magnitude of the induced emf is equal to the rate of change of magnetic flux, so its maximum values occurs when the flux curve has its greatest slope. The induced emf goes through zero when the flux curve has zero slope. We observe a 90o phase shift between flux and induced emf.

## Under what conditions the magnetic flux linked with a circuit is zero?

When plane of coil is along the direction of field, the magnetic flux linkedwith a coil is zero.
