What is the object that creates a magnetic field by running a current through a coil of wire?

Which is true electric current running along a wire can be used to produce magnetic force or moving electrons through a magnetic field can produce an electric current?
They're both true, but I'm not comfortable with the way they're stated. I would have said: -- Electric current through a wire produces magnetic force. -- Moving electrons constitute an electric current, whether or not they're moing througha magnetic field.
What is the relationship between magnetic force and distance?
-- A current flowing through a conductor creates a magnetic field around the conductor. -- Moving a conductor through a constant magnetic field creates a current in the conductor. -- If there's a conductor sitting motionless in a magnetic field, a current flows in the conductor whenever the strength or direction of the magnetic field changes.
How does a audio speaker work?
an audio speaker works by an electro magnetic coil that vibrates when a sound wave or current is running through it. thats what makes the sound.
What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
What changes an electoromagnets magnetic field?
the direction of current through the wires sorounding the solenoid

What is the relationship between magnetic fields and electricity?
-- A current flowing through a conductor creates a magnetic field around the conductor. -- Moving a conductor through a constant magnetic field creates a current in the conductor. -- If there's a conductor sitting motionless in a magnetic field, a current flows in the conductor whenever the strength or direction of the magnetic field changes.
A device that produces a magnetic field by an electric current?
Any device with an electrical current will create a magnetic field. A tube of wire coils with a current running through it is called a solenoid and it will produce a magnetic field through the inside of the tube, as well as around it... Sorry, not much for physics.
How does an elctro magnet work?
by running electric current all through a wire a magnetic field is created
What describes the production of an electric current by moving a loop of wire through a magnetic field or moving a magnet through a wire loop?
moving a loop of wire through a magnetic Field. The rotation of a coil of copper wire trough a magnetic field changes magnetic field as "seen" from the coil inducing an alternating current.

How is Electricity used to make magents?
electricity running through wires creates a small magnetic force, so wires are spooled and a current is run through them
What is magnetization current?
There is no magnetic current because there are no magnetic charges.
What is trapped energy of inductor?
An inductor resists a change in current. It does this by converting the current into a magnetic field. If the current then changes, the collapsing or increasing magnetic field will buck the attempted change through electromagnetic energy conversion.
What is electromegnetic?
an electromagnet is created by wrapping wire around a core, like iron. Then, by running a current through the wire, you can create an magnetic field.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
