When an electrical 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.
An electrical current can be induced in a wire by a changing magnetic field passing through the conductor. This phenomenon is known as electromagnetic induction, and it is the basis for the operation of generators and transformers. Moving the wire through a magnetic field or changing the magnetic field around the wire can result in the generation of an electrical current.
Yes, a wire with no current flowing through it does not produce a magnetic field. Current flow is required to generate a magnetic field around a wire.

A current-carrying wire does produce a magnetic field around it according to Ampere's law, which states that a current generates a magnetic field. This phenomenon is the basis for the operation of electromagnets and the magnetic field produced is directly proportional the current flowing through the wire.
All electrical circuits produce a magnetic field around the wires when a current is travelling. If we want to generate a large field, we can coil the wire. Such a coil is called a solenoid.
Magnets create a magnetic field without the need for electricity. However, magnets and electricity are related as moving electrical charges (current) can produce a magnetic field, and vice versa (electromagnetism).
they produce a current the magnetic field has to turn motion into that current. the gas coal or water pass on that current to the magnetic field.
If a conductor moves in a magnetic field, a voltage will be induced. This can be tapped to get an electrical current.
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
Faraday discovered that wire carrying a current, electrons, has an electromagnetic field around it.
