An electric current through a wire produces a magnetic field around the wire due to the movement of electric charges. This phenomenon is known as electromagnetism and is a fundamental principle in physics. The strength of the magnetic field is directly proportional to the magnitude of the current flowing through the 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.
How does an electric current produce a magnetic field?
When an electric current flows through a wire, it creates a magnetic field around the wire. This is because the moving electric charges in the current generate a magnetic field according to the right-hand rule of electromagnetism. The strength of the magnetic field is directly proportional to the amount of current flowing through the wire.
Why does the current flow through wire?
Current flows through a wire when there is a difference in electric potential between two points. This potential difference creates an electric field that drives the flow of electric charge (current) through the wire.
What device works by rotating a wire coil withing a magnetic field to produce electric current?
An electric generator works by rotating a wire coil within a magnetic field to produce electric current through electromagnetic induction. This process converts mechanical energy into electrical energy.
What is called electricity flowing through wire?
Electricity flowing through a wire is called an electric current. This current is the movement of electric charge carriers, such as electrons, through the wire in a specific direction.

Who was the firs person to produce an electric current bby moving a wire through a magnetic field?
Michael Faraday
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
When a electric current flows through a wire it creates a?
When an electrical current flows through a wire it creates what is called an Electro Magnetic Field.A magnetic field is create when an electric current flows through a wire.
What happens when electric current is passed through Cu wire?
When electric current is passed through a copper (Cu) wire, the free electrons in the wire start to move in the direction of the current flow. This movement of electrons constitutes an electric current, which generates heat due to resistance in the wire. The wire may also produce a magnetic field around it as the electrons move.
What is called electricity flowing through wire?
Electricity flowing through a wire is called an electric current. This current is the movement of electric charge carriers, such as electrons, through the wire in a specific direction.
What happens to a wire when and electric current passes through it?
When an electric current passes through a wire, the wire heats up due to the resistance in the material. The current causes electrons to flow through the wire, creating a magnetic field around it. This effect is used in electromagnets and electric motors.
