Field Effects
Our range of field effects resources contain safely encased iron filings and are used to observe the effects of invisible magnetic fields. By holding a magnet to the surface of the Magnetic Field Pattern Window, the iron filings inside become magnetised and cluster into the lines that show the magnetic field which is otherwise invisible to the human eye.
