When current carrying wire is wrapped around an iron core what can it create?
It creates a magnet and magnetism.
What was wrapped around an iron bar to create the first electromagnet?
Coils of wire

Does electric current create magnetic fields?
Yes, electric current does create magnetic fields
Does a coil carrying electric current create a magnetic field?
No, The magnet rotates/moves through the coil, inducing a current into the coil by disturbing the coils magnetic field. A transformer works the exact same way.

How is a magnetic force in an electromagnet created?
An electromagnet uses electricity to create the magnetic field. Moving charges create magnetic fields. Knowing that, if we have a lot of copper wire (with a suitable insulator) wrapped around an iron core, we can send direct current through that wire, and it will create a magnetic field. The magnetic field will magnetize the iron core, and the core becomes a magnet. Wrapping wire around a nail and connecting a battery to the ends of the wire will make a simple electromagnet.
What does an enameled wire that's wrapped around an iron nail connected to an electrical circuit create?
An electromagnet.
What is a device that has an iron center wrapped in coil of wires?
This is a basic description of an electromagnet. Apply a voltage (direct current) to the coil, and a magnetic field will develop around the coil and be "conducted" through the iron core to create that electromagnet.
Why christo wrapped his artwork and what is the relevancy to wrapped an object?
christo wrapped his artwork because he wants to create another intrepetation about inviromental art.
Can be produced by electric currents going around?
Sending electricity though a copper wire wrapped round an iron core will create an electro-magnet.
How can magnetic fields be used to create an electric current?
Move wires rapidly through the magnetic field so that they "cut" the field lines will create an electric current in the wires. This is the method used in alternators, generators, magnetos, and read heads on disk drives and tape recorders.
Would applying current through a coil which has a permanent magnet at its center increase the magnetic field from the magnet?
no. applying an electrical current to a coil wrapped around a magnet would create a force, which would move the magnet one way or another. to fully understand how to position coils and magnets to get the result you want, google the 'right hand thumb rule'
