Type of Magnetic Material

Every material has a unique composition that defines its magnetic behavior. Some materials get attracted towards a magnet and are called magnetic materials. Based on the magnetic properties held by each material, they are classified into different types.

Question

If an aluminum sheet is held between the poles of a large
bar magnet, it requires some force to pull it out of the magnetic field even though the sheet is not ferromagnetic and
does not touch the pole faces. Explain.
