Figure CQ30.10 shows four permanent magnets, each having a hole through its center. Notice that the blue and yellow magnets are levitated above the red ones. (a) How does this levitation occur? (b) What purpose do the rods serve? (c) What can you say about the pole of the magnets from this observation? (d) If the blue magnet were inverted, what do you suppose would happen?
