A copper piece cannot be changed into magnets.why
Answers
Answer:
The d-orbital can hold a maximum of 10 electrons, so copper has no unpaired d-electrons. ... Pure copper can't be made into a magnet because it doesn't have these magnetic domains.

Answer:
A piece of copper is diamagnetic. Diamagnetism is the property of an object which causes it to create a magnetic field in opposition to an externally applied magnetic field, thus causing a repulsive effect. Specifically, an external magnetic field alters the orbital velocity of electrons around their nuclei, thus changing the magnetic dipole moment. According to Lenz's law, these electrons will oppose the magnetic field changes provided by the applied field, preventing them from building up. The result is that lines of magnetic flux curve away from the material. In most materials, diamagnetism is a weak effect, but under conditions of superconductivity, which only some materials may obtain, a strong quantum effect can emerge wherein the lines are completely blocked, excluding a very thin layer at the material's surface. Diamagnets are materials with a magnetic permeability less than μ0. (a relative permeability less than 1).
