Is Aluminum Magnetic? - University Of Maryland

Is Aluminum Magnetic? In our everyday experience aluminum doesn't stick to magnets (neither does copper). The question of whether aluminum is magnetic is a bit more involved and depends what you mean by the term "magnetic". Most matter will exhibit some magnetic attraction when under high enough magnetic fields.

electromagnetism - Why is copper diamagnetic? - .

They behave as electric current loops that orient themselves in a certain way in the external magnetic field. Copper has lots of these complete shells, so the diamagnetic contribution is large. There's also the opposite contribution from the unpaired electron but it's just one electron and the paramagnetic contributions "scale" with the number of these electrons and one is too few.
