Magnetic attraction. Image 2 of 3. Iron filings (black specs) sprinkled on a surface with two bar magnets underneath it. Bar magnets have a north and a south pole. Unlike poles attract each other and the filings show the attraction as field lines joining the ends of the magnets. The lines do not actually exist,as the magnetic field is continuous,but attractions between the filings make them arrange themselves into thin arcs. For an image of the field shape between repelling magnets,see A230/0167 | |
