FIGURE 6. UNLIKE POLES.
It can be proved that the lines of force do have a direction of movement by using two magnets and
iron filings. First, place the magnets in iron filings so unlike poles are facing. Notice that the lines
of force between the unlike poles combine to increase the strength of the magnetic field between
the two magnets. This indicates that the lines of force between unlike poles flow in the same
