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?
