what flowed along with the iron nail? how did it affect the electromagnetism produced by the iron nail?

Answer:

Current flowed along with the iron nail. A magnet made from just a coil of wire isn't very strong. But when you coil the wire around an iron nail, the magnetic domains inside the nail line up and make a strong, temporary magnet. If you disconnect the wire, the magnetic field disappears and the nail is no longer a magnet.

hope it helps^^
