Can electric field exist without charge?

Q1,Electric fields are areas around a charge so yes there can be an electric field at a point where there is no charge. E=kq/r^2. No there can not be a charge with no field.

Does electric field exist in an empty space?

Yes, according to Maxwell's equations an electric field exists in empty space.

In which field electric field can exist in the absence of?

Without the electric field, the magnetic field exists in permanent magnets and electric fields exist in the form of static electricity, in absence of the magnetic field.

Can magnetic field exist without charge?

No, it is not possible to create magnetic waves without an electric field being present. Electric fields are created by electric charges. For instance, if you statically charged up a balloon by rubbing it on your hair, the balloon creates an electric field. Magnetic fields are created by magnets.

Can electric field exist without a magnetic field?

So, both the electric and magnetic fields exist without each other. So, we conclude that magnetic fields can exist without electric fields and electric fields can also exist without magnetic fields. Note: Electric and magnetic fields are both the components related to electromagnetic waves.

No, Changing Electric Fields DON'T Cause Magnetic Fields; The Real Origin of Electromagnetic Waves

Can electric field exist in vacuum why?

No, an electric charge cannot exist in a vacuum. Electric charge is associated with charged particles, and if they existed in some part of space it wouldn't be a vacuum. ... Electric current is an amount of electrons in an electric conductor. If you have such a conductor in vacuum you have no problems.

Does the electric field exist?

An electric field is said to exist in the region of space around a charged object. This charged object is the source charge. When another charged object, the test charge, enters this electric field, an electric force acts on it. The electric field is defined as the electric force on the test charge per unit charge.

Why there is no electric field inside a 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 is electrostatic field zero?

The electrostatic field should be zero inside a conductor because in a conductor, the charges are present on the surface. Therefore, the charge inside should be zero. Also, according to the Gauss theorem, the electrostatic field is zero.

Why is electric field zero inside a sphere?

All the charges lie on the surface of the charged sphere. If a gaussian surface is drawn within the sphere, there will not be any charge within the surface. Therefore, the electric field strength inside a sphere is zero.

Why is electric field real?

Electric fields are caused by electric charges, described by Gauss's law, and time varying magnetic fields, described by Faraday's law of induction. Together, these laws are enough to define the behavior of the electric field.

Is electric field real or imaginary?

Actually, electric fields are real. Using complex exponentials bears no advantage other than convenient calculation. The interpretation usually is that the imaginary part is discarded and only the real part is taken to be, well, real.

In which of the following situation does electric field exists?

An electric field exists in the space between two charged metal plates.

Can electricity spark in space?

You can pass electricity through a vacuum, as a stream of charged particles, but there won't be a spark. Older style televisions (like mine) with a "cathode ray tube" (CRT) do precisely this. A beam of electrons is boiled off from a coil and then accelerated through a vacuum at high speeds towards the screen.

Is electric field zero in vacuum?

Gauss's law in differential form states that divergence of electric field is proportional to charge's volume density. From Gauss's law it is concluded that in vacuum, where no electric charges are present, divergence of electric field and closed surface integral of electric field are zero.

Why is there no charge in vacuum?

A vacuum is an insulator because of the work you have to do to put mobile electric charges into it. A conductor like a copper wire already has mobile electrons, so it takes very little work to get them moving in a current.

Is electric field everywhere?

Electromagnetic fields are present everywhere in our environment but are invisible to the human eye. Electric fields are produced by the local build-up of electric charges in the atmosphere associated with thunderstorms.

Is electric charge real?

Electric charge, which can be positive or negative, occurs in discrete natural units and is neither created nor destroyed. Electric charges are of two general types: positive and negative. Two objects that have an excess of one type of charge exert a force of repulsion on each other when relatively close together.

Do magnets have an electric field?

Magnets only work on motion

A single particle with electric charge, sitting all by its lonesome, not doing anything interesting, will generate an electric field. This field surrounds the particle on all sides and instructs other charged particles how to move in response.

What is electric field made of?

In a moving reference frame, a magnetic field appears instead as a combination of a magnetic field and an electric field, so electric and magnetic fields are made of the same "stuff" (photons). Some electromagnetic interactions involve "real" photons with definite frequencies, energies, and momenta.

Does DC current produce electric field?

DC electricity produces static electric and magnetic fields, but these fields have very different properties from AC Electric Magnetic Fields (EMF*). For example, because the EMF from AC lines are time varying, they can induce currents and voltages in nearby conductive objects.

What does electric field depend on?

The electric field strength is dependent upon the quantity of charge on the source charge (Q) and the distance of separation (d) from the source charge.

Can electric field inside a conductor be non zero?

The answer is NO. Electric field inside a conductor is always zero. Reason: The electricity conducting free electrons are only present on the external surface of the conductor. Resultantly, electric field is only present in the external surface of the conductor.

Why there is no charge inside the spherical shell?

The whole charge is distributed along the surface of the spherical shell. There's no charge inside. Therefore, q-enclosed is 0. Since q-enclosed is 0, therefore we can say that the electric field inside of the spherical shell is 0.
