here I have an activity to show u why repulsion is a sure test for magnetism
MATERIALS NEEDED:2 bar magnets ,thread,a woodstand
PROCEDURE: take a magnet suspend it with the help of a thread.
Now bring one end of a metallic bar near one pole of the suspended magnet at a time if one end of the mettalic bar is attracted and the other one is repelled the metallic bar is a magnet .if both the the ends of the mattalic barare attracted then it is not a magnet.
Hence we can tell that repulsion is the sure test for magnetism.
