Typically, copper wire itself is not permanently magnetic, so it is unlikely that it will be “magnetized.” Copper is a very conductive metal and does not generally remain magnetic.
Magnetism is caused by the movement of charges and the arrangement of atoms in the internal microstructure of matter. Some special metals or alloys (such as iron, nickel, cobalt, etc.) can maintain magnetism for a certain period of time after being affected by a magnetic field.
Copper itself is not a long-term magnetic material, so it is not suitable for making magnets or retaining magnetic fields. If you want to make magnetic copper wire, usually the best way is to wrap a strong permanent magnet around the copper wire, or wrap the copper wire in a material that retains its magnetism over time.
In general, copper wire itself is not a good choice for making magnetic materials. If you need a material that can maintain magnetism, it is recommended to choose magnetic metals or alloys such as iron, nickel, and cobalt.
