Iron in Cereal is more about nutrition and just uses a magnet to get iron filings; Visualizing Magnetic Fields in 3D gives an idea of the shape of the fields around magnets using iron filings; Dropping Magnets and Making Fields uses the knowledge of magnetic fields to connect electron motion, electricity, and magnets; and Kitchen Magnet Detection goes back to magnetic fields by feeling the "bumps" of a magnet.
