PPT-Magnets Poles of a magnet are the ends where objects are most strongly attracted

Two poles called north and south Like poles repel each other and unlike poles attract each other Similar to electric charges Magnetic poles cannot be isolated If a permanent magnet is cut in half repeatedly it will still have a north and a south pole.
