This, in turn, creates an attraction between the two magnetized objects.
What is it called when magnets repel?
The ends of a magnet are called its poles. … If you line the magnets up so that two of the same poles face each other, the magnets will push away. This is called repulsion. Opposite poles attract each other, but similar poles repel. The Earth acts like a giant magnet.
