EXAMPLE OF USE: Magnetic field produced by a permanent magnet

This classic experiment shows magnetic lines of force produced by various combinations of bar-shaped magnets.

One of the simplest ways for showing the behaviour of the lines of force of a magnetic field is the use of iron filings. The small iron fragments orient themselves like small magnetic needles along the direction of the field, demonstrating the actual lines of force.

This is a very interesting demonstration showing the lines of force of a magnet using iron filings. Students can easily see where lines of force are greater, simply by the greater density of the iron filings and how they line up, and a very simple way to show how the North and South poles of a magnet differ.
