Some fundamental particles in nature, happened to have an electric field. We just named one of them "electron". That's the simple answer.
From an engineering point of view, there is no such thing as an electric field or electric line of force. Its a classical physics construct that we came up with, in order to explain what happens when charged particles interact with each other.
Why do some particles have charges in the first place? Its because of some complex quark level interaction that I don't yet understand. Thus we have positive and negative charges, which attract each other, while like charges repel and we made up "electric lines of force" to explain them.

What do mobile electrons produce?
Mobile electrons produce an electric current when they flow through a conductor in response to an applied electric field. This movement of electrons is the basis for electricity generation and transmission in various electronic devices and circuits.
How are free electrons impelled along a conductor?
Free electrons in a conductor are impelled by an electric field created when a voltage is applied across the conductor. This electric field exerts a force on the free electrons, causing them to drift in the direction opposite to the electric field. As the electrons move, they collide with lattice ions, which impedes their flow, resulting in resistance. The overall movement of these electrons constitutes an electric current.
When electrons are rearranged in an object by an electric field the object is charged by what?
When electrons are rearranged in an object by an electric field, the object is charged by gaining or losing electrons. If an object gains electrons, it becomes negatively charged, and if it loses electrons, it becomes positively charged.
What is the flow of electrons is called?
The flow of electrons is called electric current. It is the movement of electric charge through a conductor, such as a wire, in response to an electric field.
Can an electric current produce a field magnetism around it?
yes. electric current low always generates a magnetic field.
Can moving electrons through a magnetic field can produce an electric current?
Yes, a moving electron in a magnetic field can induce an electric current. This is the principle behind electromagnetic induction, where a changing magnetic field induces an electric current in a conductor.
What causes a magnetic field to be set up around a wire?
Passing an electric current through a wire will produce an external magnetic field. This is because the electrons have spin and this spin is what produces the field. Spinning electrons (of certain characteristics) also produce the magnetic field of permanent magnets. And no spinning electrons, no magnetic field.
What do mobile electrons produce?
Mobile electrons produce an electric current when they flow through a conductor in response to an applied electric field. This movement of electrons is the basis for electricity generation and transmission in various electronic devices and circuits.
How do electric currents produce magnetic fields?
Electric currents produce magnetic fields through the interaction of moving electric charges. When an electric current flows through a conductor, such as a wire, the moving electrons create a magnetic field around the conductor. This magnetic field is generated by the alignment of the electrons' spins and their movement in a particular direction. The strength of the magnetic field is directly proportional to the amount of current flowing through the conductor.
In a electric field and stream of electrons will behave in what way?
In an electric field, electrons will experience a force and move in the direction opposite to the field (from negative to positive). The electrons will accelerate in this direction.
When an electric field is applied to a metallic crystal the movement of electrons is?
When an electric field is applied to a metallic crystal, the movement of electrons is towards the direction opposite to the field. This is because electrons are negatively charged particles and will experience a force in the opposite direction to the electric field. This movement of electrons constitutes an electric current.
How does a changing magnetic field produce an electric field according to electromagnetic theory?
According to electromagnetic theory, a changing magnetic field induces an electric field. This phenomenon is known as electromagnetic induction, where the changing magnetic field creates a force that causes electrons to move, generating an electric current.
How moving electrons of space is being deflected by an electric field?
When an electric field is applied to moving electrons in space, the field exerts a force on the electrons due to their charge. This force causes the electrons to deviate from their original path and change direction. The amount of deflection depends on the strength of the electric field and the velocity of the electrons.
In which direction does the electric force act on electrons?
The electric force acts in the opposite direction of the electric field on electrons.
Does an electric field exert a force on a beam of moving electrons?
Yes, an electric field exerts a force on a beam of moving electrons. The force exerted on the electrons by the electric field causes them to accelerate in the direction of the field. This acceleration can be measured and explained using Coulomb's law and the equation for the force on a charged particle in an electric field.
When does a copper wire produce a magnetic field?
A copper wire produces a magnetic field when an electric current flows through it. This is due to the interaction between the moving electrons in the wire and the magnetic field they generate.
What are two ways to produce electric fields electric fields are produced by charged particles or by changing magnetic fields?
One way to produce an electric field is through the presence of charged particles. When charged particles, such as electrons or protons, are stationary or in motion, they generate an electric field around them. Another way to produce an electric field is through changing magnetic fields. According to Faraday's law of electromagnetic induction, a changing magnetic field induces an electric field, causing the flow of electric charges.
