What is the electric field in a current carrying conductor?

The electric field inside a current carrying conductor is zero be because the charges are distributed on the surface of the conductor. But, magnetic field is created around the current carrying conductor. The moving charges create a magnetic field around the conductor.

What is magnetic field due to a current carrying conductor?

The force of magnetism is due to moving charge or some magnetic material. Like stationary charges produce an electric field proportional to the magnitude of charge, moving charges produce magnetic fields proportional to the current. In other words, a current carrying conductor produces a magnetic field around it.

Does electric current produce electric field?

Yes, an electric current =does= produce an electric field. This is due to relativity, specifically the Lorentz Contraction.

Does current affect electric field?

We also are familiar with the fact that voltage difference between two points is also proportional to the electric field magnitude. This naturally implies that, current is proportional to the magnitude of electric field between the two points the current flows.

Why magnetic field is produced due to current?

A magnetic field describes a volume of space where there is a change in energy. As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire.

What is magnetic field due to an infinite line current carrying conductor?

Magnetic field due to an infinitely long straight current carrying wire. B=(2πr)μ0I where B is the magnitude of magnetic field, r is the distance from the wire where the magnetic field is calculated, and I is the applied current.

Why there is no electric field around a current carrying conductor?

There is no E field outside the conductor due to electrons because the conductor is not charged–this means there exist an equal number of protons to every electron in the conductor. If the conductor was charged, then there would be E field outside the conductor due to that charge.

What is electric field current?

The electric current i is the rate of flow of charge (dq/dt) and the unit is ampere = coulomb/sec. An electric field exists and can be observed in the space around a single charge or a number of charges.

What is magnetic field due to a current through a circular loop?

Magnetic Field Pattern due to a Circular Loop Carrying Current. Each segment of circular loop carrying current produces magnetic field lines in the same direction with in the loop. The direction of magnetic field at the centre of circular coil is perpendicular to the place of the coil. i.e. along the axis of the coil.

Is electric field the same as current?

Electric current is equal to one direction moving electrons in closed circular loop. We visualize the electric force (the “negative” force of the electrons) with the electric field. Also the protons have electric force. An electric field is the space around charged particle which it effects.

Is there an electric field outside of a current carrying wire?

Yes there is an electric field outside of a current carrying wire, in a direction along the wire axis (i.e. parallel to the wire). This is true in both the AC and DC case. There is also of course a magnetic field in the azimuthal direction.

Is there a magnetic field around a conductor while current flows?

A more direct answer to your question: Yes, there are both electric fields and magnetic fields around the conductor while there’s current flowing through it. This is guaranteed by Maxwell’s equations, and the fact that current is proportional to the electric field in a conductor.

Does a current carrying conductor have any net charge?

Thus, the current carrying conductor will not be charged (i.e. it would not have any net positive or negative charge). Remember a dipole has zero net charge, but it does have electric field around it (although the net electric field around a dipole drops to insignificance as the distance increases to multiples of the dipole separation).

Is Griffiths’ E field outside a current carrying wire due to static?

In a Griffiths EM problem, he treats the E field outside a current-carrying wire as if it were due to a static charge distribution. Is this a valid approximation? Upon google-searching i get very vague/contradicting answers, so any help is appreciated! Outside the wire, I think there should be no E field, seeing that the net charge is 0 (?).
