Depends on exactly what its made out of, the diameter and it's resistance per metre. Forced air,refrigeration or water cooling can assist. Superconducting wire ,when kept very cold, can pass thousands of Amps and can be as fine as hair.

A magnet can generate an electric current in a wire if the magnet is close enough to the wire and if the magnet is also?
strong
How can magnet produce current?
Faraday found that a wire passed by a magnet induces a current in the wire. This led to making an electrical generator.
What is a magnet that is creadted from electric current through a wire?
Electro-Magnet
What will be attracted to ( or repelled by) a magnet?
a copper wire carrying current and another magnet.
What is a magnet created when electric current flows through a coil of wire?
A magnet created when electric current flows through a coil of wire is called an electromagnet.
If a magnet is held close to a coil of wire will it cause current to flow?
Yes, but only if the magnet or the wire are kept moving.
Is a solenoid a coil of wire that has a current?
YESA solenoid is a coil of wire, which turns into a magnet when a?current?flows through
Will a copper wire not carrying a current be attracted to a magnet?
No, a copper wire that is not carrying a current will not be attracted to a magnet. Copper is not a magnetic material, so it does not interact with magnetic fields in the same way that magnetic materials like iron or nickel do.
A horseshoe magnet is moved back and forth across a piece of copper wire an electric current is detectable in the wire?
yes, it will be very small but the inductance from the magnet should stimulate a current in the wire as it will cause electrons to move.
What happens to copper wire because of the moving magnet?
The copper wire carries an electric current.
How can sound be changed into electric current?
The most common way is with a magnet and a coil of wire. Have either the magnet or the coil (it doesn't matter which) fixed in place and the other one attached to a membrane that will vibrate with the sound. When a magnet moves past a coil of wire, it causes an electric current in the wire.
How can a magnet field be produced around a wire?
By passing a current threw it.
