The conference of over 100 women from 17 countries, representing unions, socialist parties, working women's clubs, and including the first three women elected to the Finnish parliament, greeted Zetkin's suggestion with unanimous approval and International Women's Day was the result.
Magnets are pieces of metal that have the ability to attract other metals. Every magnet has two poles: a north and a south. Much like electrical charges, two similar magnetic poles repel each other; while opposite magnetic poles attract each other. Magnets have a continuous force around them that is known as a magnetic field. This field enables them to attract other metals. Figure 1 illustrates this force using bar and horseshoe magnets. The shape of the magnet dictates the path the lines of force will take.
If you've ever played with magnets, then you definitely know that they exert an invisible force on each other. However, there is a very specific direction to these forces depending on which poles are near each other. Another fundamental property of magnets is that similar poles repel, while opposite poles attract.
