# Best answer: How strong is a strong electric field?

Contents

As determined by the vibrational Stark effect of a nitrile-bearing fluorescent probe, the strength of the electric field is found to be on the order of 107 V/cm. This strong electric field aligns probe dipoles with respect to the interface.

## What is considered a strong electric field?

ionization chambers. …free electron in a strong electric-field. When the strength of the field is above about 104 volts per centimetre, an electron can gain enough energy between collisions to cause secondary ionization in the gas. After such an ionizing collision, two free electrons exist in place of the original one.

## Is there a limit to how strong an electric field can be?

Is there a limit to electric field, YES, according to QED. At an electric field of about 10^16 V/m the vacuum breaks down with pair production. This has the effect of shielding such naked charges.

## At which point electric field is strongest?

The magnitude of an electric field is directly proportional to the density of electric field lines. When the lines are closer to each other, the >electric field is the strongest; when the filed lines are far apart from each other, the electric field is the weakest.

## How do you know which electric field is stronger?

The relative magnitude of the electric field is proportional to the density of the field lines. Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest. If the lines are uniformly-spaced and parallel, the field is uniform.

## Can the electric field be negative?

Electric field is not negative. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field.

## Is magnetic or electric force stronger?

The one created by electric field is independent form particle velocity, while the Lorentz force is proportional to particle velocity. Thus at v=0 the electric part of force acting on particle is infinitely stronger than magnetic part.

## What is the strongest magnetic field possible?

That is far and away the most powerful magnetic field ever detected in the universe – for reference, the strongest magnetic field created in the lab so far is a “mere” 1,200 Tesla.

## Which of these most affects the strength of an electric field?

Strength of an electric field is affected by the distance from the charge and the amount of charge that produces the field.

## Which point is the electric field the weakest?

Electric field strength is greatest where the lines are closest together and weakest where lines are furthest apart.

## Why can electric fields never cross?

Electric field lines cannot cross. … This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.

## What is the magnitude of an electric field?

The magnitude of the electric field is simply defined as the force per charge on the test charge. The standard metric units on electric field strength arise from its definition. Since electric field is defined as a force per charge, its units would be force units divided by charge units.

## Is an electric field stronger closer?

Electric fields around isolated charges – summary

The field lines are closer together where the field is stronger. Look at the diagram below: close to the central charges, the field lines are close together. This is where the electric field is strongest.

## How is the strength of an electric field indicated with field lines?

The strength (magnitude) of the electric field is indicated by the number of electric field lines in a region – lots of closely spaced lines means a strong electric field, a few widely spaced lines means a weak electric field. The magnitude of the electric field is proportional to the number of electric field lines.

## How is the magnitude of the electric field represented by electric field lines?

As for the magnitude of the field, that is indicated by the field line density—that is, the number of field lines per unit area passing through a small cross-sectional area perpendicular to the electric field. This field line density is drawn to be proportional to the magnitude of the field at that cross-section.
