Solution

Dear Student

Magnets are only attracted to special metals. Iron, cobalt and nickel are magnetic.

Metals that have iron in them attract magnets well. Steel is one. Metals like brass, copper, zinc and aluminium are not attracted to magnets.

Non-magnetic materials such as wood and glass are not attracted to magnets as they do not have magnetic materials in them.

But copper is so weakly magnetic that we can't observe it without very, very large magnetic fields. So there won't be any effect on copper in the presence of magnetic field.
