Is Aluminum Magnetic? - University Of Maryland

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. But under normal circumstances aluminum isn't visibly magnetic. This is easily tested by putting a very strong neodymium magnet near aluminum can.
