Question about the physics behind magnets?

My physics teacher told us to try this at home and im confused as to why this happensI have two magnets in the shape of a disk they are both about 1in in diameter by 1/3in in heightI took a block of Styrofoam and placed a magnet on each side of the Styrofoam and both magnets were able to attract each other through the StyrofoamI then tried the same thing but with a block made of aluminum that was the same size and shape of the Styrofoam and the magnets were not able to attract.Can someone explain why this is so? I have a hunch but dont know if its rightIs it because the aluminum is more dense then the Styrofoam?

Answer:

No, density has little to do with itAluminum is a conductor so it shields from the magnetic attractionNot as good as an iron piece would do, but better than the plastic.
Did you put go out with friends? What's a sophomore?
