Magnetic Fields

This picture was taken when two magnets were placed beneath a white sheet of paper before sprinkling iron metal filings on top. The iron filings automatically aligned themselves along the field lines that connect the magnet's North and South poles. Since Iron is a ferromagnetic element, these types of elements have interactions between electrons, and this tends to line up their magnetic movements with their neighbour's, as the iron filings did around the magnet. This is how the iron filings showed the magnetic fields of the magnets.
