How does a magnet work?
Attraction and Repulsion of Magnetic Poles
When two magnets are brought close to each other, they are either pulled towards each other, or pushed away from each other. When the magnets are pulled towards each other, they are said to attract each other. When they are pushed away from each other, they are said to repel each other. Whether the magnets attract or repel depends on which poles of the magnets are facing each other.
When like poles of the magnets (N-N or S-S) are brought close to each other, they repel. This is called repulsion.
When unlike poles of the magnets (N-S or S-N) are brought close to each other, they attract. This is called attraction.
