# Is electric field zero inside conductor?

## Is electric field zero inside conductor?

Electric field is zero inside a charged conductor. For a charged conductor, the charges will lie on the surface of the conductor.So, there will not be any charges inside the conductor. When there is no charge there will not be electric field.

### Why must there be an electric field in a current carrying conductor?

Expert-verified answer because you know two opposite nature charge must apply coulombic force on each other . Also we know, Force , F = qE ,where q is charge and E is electric field . Hence, due to electric force , field must introduce inside the current carrying conductor.

#### Why electric field lines do not pass through conductor?

The net electric field inside a conductor is zero. Therefore, the electric field lines do not pass through a conductor.

Why is the field inside a conductor zero?

In electrostatics free charges in a good conductor reside only on the surface. So the free charge inside the conductor is zero. So the field in it is caused by charges on the surface. Since charges are of the same nature and distribution is UNIFORM, the electric fields cancel each other.

Why current carrying conductor does not produce electric field?

According to the laws of electromagnetism, a current carrying conductor is a neutral species unless an external charge or electric field is applied to it. So, the conductor does not induce any electric field around itself. However, a magnetic field is produced in the surroundings in accordance with Biot-Savart’s law.

## When magnetic field due to a current carrying conductor is zero?

The force exerted on a current carrying wire placed in a magnetic field is zero when angle between the wire and the direction of magnetic field is. We know that sin 180° is 0. Therefore, the force exerted on a current-carrying wire that is placed in a magnetic field is zero.

### How does an electric field pass through a conductor?

#### Why are electric field lines perpendicular to the surface of a conductor?

Because electric field lines must be perpendicular to the surface of conductor, otherwise there would be a non zero component of electric field along the surface of conductor and charges could not be at rest.

Does current produce an electric field?

So, if you have a circuit and you send AC current through (AC = Alternating current) so that the electrons move back and forth, they will create a changing electric field. This produces a magnetic field (because that’s what the universe does). Similarly a changing magnetic field creates an electric field.

Why electric current through a conductor produces only magnetic field?

Electric field that should be created when a steady current is passing through a part of a circuit, then the conducting cylindrical wire will not produce an electric field but only magnetic field as there is flow of just electrons and not protons.

## What is magnetic field due to current carrying conductor?

The magnetic field produced due to a current-carrying conductor has the following characteristics: It encircles the conductor. It lies in a plane perpendicular to the conductor. Reversal in direction of current flow reverses the direction of the field.
