An electric current produces a combination of three effects. These are the heating effect, the chemical effect, and the magnetic effect.
The unit of measurement of current, the ampere(A), cold be defined in terms of any of these three effects. However, in SI, the ampere is defined in terms of its magnetic effect -i.e. the force of attraction or repulsion created by the magnetic fields surrounding two, parallel, current-carrying conductors. Prior to its present definition, current was defined in terms of its chemical effect -i.e. the amount of silver deposited by electrolysis over a given period of time.

How do protons attract electrons through a wire?
firstly you need a battery or a cell to produce a p.d or to produce current (flow of electrons). the opp charges will always attract each other. therefore, the electrons travel through the wire from the -ve terminal of the battery to the +ve.
How does a generator produce an electric current?
Electromagetism is a unified force. A magnetic field that is moving relative to a wire will cause electrons within the wire to move. Less common is a moving wire in a stationary magnetic field, but the relative movement between the wire and magnetic field induces the same movement of the electrons within the wire. This action of moving the electrons in a wire (or Armature) produces the electric current that may then be used to power a circuit.
What is the connection between magnetism and electricity?
The connection between magnetism and electricity is electromagnetism. An electric current creates a magnetic field, and a changing magnetic field induces an electric current. This relationship forms the basis of many technologies, such as electric motors and generators.
Does copper wire produce electricity?
Copper wire itself does not produce electricity. However, when copper wire is part of an electrical circuit and connected to a power source such as a battery or generator, it can transfer electricity by allowing the flow of electrons through it.
What is the relationship between electron and magnetism?
Electrons have a charge. Any moving charge creates an electric field, e.g. electricity moving through a wire causes a magnetic field around the wire, or the earth rotating creates a magnetic field which causes a compass to point north. Similarly all electrons have a spin factor. similar to the earth rotating, the spin of electrons create a magnetic field around the electron.
Where do moving electrons come from when making an electromagnet?
Moving electrons in an electromagnet come from the flow of electric current through a wire or coil of wire.
Where do the moving electrons come from when making an electromagnet?
When making an electromagnet, the moving electrons come from the flow of electric current through a wire or coil of wire.
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.
Is a current-carrying wire electrically charged because of the electrons moving in it?
A current-carrying wire is not electrically charged because of the movement of electrons. The wire as a whole remains electrically neutral even though the electrons are moving within it. The flow of electrons is what constitutes an electric current.
From where do the moving electrons in an electromagnet come?
The moving electrons in an electromagnet come from the flow of electric current through a wire or coil.
What does a turbine spin around to make electrons flow in a wire?
Not around... moving THROUGH a magnetic field forces electrons to flow through a wire.
What Energy of electrons moving through a wire is called?
The energy of electrons moving through a wire is called electrical energy. This energy is typically converted into other forms, such as heat, light, or mechanical energy, depending on the device or system the wire is connected to.
What particles are moving from atom to atom in a wire?
In a metal wire electrons go and go and go! when conducting electric current.
What are electrons moving in a current is called?
The speed at which electrons flow along the wire is called the current. The measurement for current is amps.
What is inside a generator that makes electricity?
Coils of wire and a magnet. When magnetic lines of force move across a wire, it causes electrons in the wire to move. Those moving electrons are electrical current. In a generator, either the magnet or the coils of wire spin.
How do protons attract electrons through a wire?

How can you produce current in a wire with a magnet that is stationary?
When a magnet is stationary near a wire, it can produce current in the wire through electromagnetic induction. This happens when the magnetic field from the magnet interacts with the electrons in the wire, causing them to move and create an electric current.
