The Attempt at a Solution


Aluminum and copper has less magnetic property while iron is good magnetic material. I cannot understand why the paper clips should fall when iron is inserted and not fall when copper is inserted.

The magnetic lines of force pass through non magnetic materials like the cardboard and non-ferrous metals. They interact with magnetic metals like the iron in the paperclips. But a sheet of magnetic metal will cause the lines of force to redirect, and they are no longer passing through the paperclips.
