A copper rod of mass m and length L is hung from the ceiling using two springs of spring constant k. A uniform magnetic field of magnitude (displaystyle B_0) pointing perpendicular to the rod and spring (coming out of the page in the figure) exists in a region of space covering a length w of the copper rod.

Yes, the purity of copper can affect its magnetic behavior. Generally, pure copper is considered non-magnetic, but impurities in the copper can alter its magnetic properties to some extent. Pure copper has a face-centered cubic (FCC) crystal structure, and its electrons are arranged in such a way that the overall magnetic moment is zero. …

Is Copper Magnetic? Copper is not magnetic in the sense that if you hold a magnet over something made of copper, it will stick to it. That said, copper does have some magnetic properties. In particular, it plays an important role with electricity and eddy currents. When a magnet draws close to copper, it creates an electrical eddy current.

As a magnet approaches copper, it alters the surrounding magnetic field. This change triggers the flow of electric currents known as eddy currents within the copper. These circular currents are crucial because they create magnetic fields that oppose the initial change in the magnetic field, aligning with Lenz's law.
