2. Aluminum is paramagnetic. Why won't a typical refrigerator magnet stick to an aluminum can?
3. Describe how bar magnets produce a force on each other
Homework Answers
2) Aluminum normally is is non-magnetic however when a external magnets tens to align the unpaired electrons then it behaves like a magnet and same with refrigerator ,but under normal conditions both are non magnetic so they wont attract

Packing material made of pieces of foamed polystyrene can easily become charged and stick to each other. Given that the density of this material is about 35 kg/m^3, estimate how much charge might be on a 2.0 cm-diameter foamed polystyrene sphere, assuming the electric force between two spheres stuck together is equal to the weight of one sphere. Express your answer using two significant figures.
