1) YES, electric fields exist and can extend/propagate through a vacuum. Reasoning: Why not there is no difference between a vacuum and space just that a vacuum has no air in it. Vacuums are still made of matter so the electric field should still extend into that space.
What is the electric field in vacuum?
Interaction between electric charges is called electromagnetic interaction, and is one of four fundamental interactions of matter. Nevertheless, the electromagnetic interaction takes the leading role among these interactions, since overwhelming majority of phenomena surrounding us have the electromagnetic nature.
Is it possible for an electric field to exist in empty space?
Yes, an electric field exists in empty space, according to Maxwell’s equations.
Can electric field exist in a vacuum explain with the help of an example?
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.
What field is present in a vacuum?
Yes, magnetic fields can exist in perfect vacuum.
How do you find the electric field in a vacuum?
Your field can then be described as E=Ez(x,y,z)ˆz. As an electrostatic field, this must satisfy Gauss’s law, which in vacuum reads ∇⋅E=∂Ez∂z=0, and means Ez cannot depend on the z coordinate. More intuitively, the electric field cannot change its magnitude along its direction in the absence of electric charge.
Why there is no charge in vacuum?
As we know electromagnetic waves are created by charges in motion or by magnetic field created by charged particles. And for the flow of field other charge carriers are required but vacuum does not contain any charged particles and how these waves are being carried forward after they have been produced from a source.
Do electric fields actually exist?
No, they do not exist. Electric field lines are only imaginary. They are the paths along which an imaginary unit charge would move when free.
Are electric fields 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.
Why can’t two electric field lines cross?
Answer: Electric field does not direct in two directions that is why electric field lines never cross over each other. … When two lines intersect each other, tangents are drawn at that point indicating two directions of electric field lines, which is impossible therefore electric field lines cannot cross over each other.
Can electric fields pass through an insulator?
The answer is “Yes”. Insulators are materials that hinder the free flow of electrons from one particle of the element to another. Whereas dielectric or insulators can be polarised by the electric field. Rather electric field passes ONLY through the insulator.
Is electric field a vector or scalar?
Electric force and electric field are vector quantities (they have magnitude and direction). Electric potential turns out to be a scalar quantity (magnitude only), a nice simplification.
