Answer 2

If any external magnetic field is present around the copper coins, they tend to push themselves or attract or move away.

• When the copper coins are placed where there are external magnetic fields,

• The above phenomena is seen because copper being metal has high repulsive forces when subjected to the external magnetic field and shows these properties.
