Magnetism

Karen places one magnet close to another magnet. When she does this the magnets move toward each other. How can Karen explain this?

• The south pole of one magnet pulls on the south pole of the other magnet.

• The north and south poles of the two magnets attract each other.

• The magnetic fields of the magnets are too weak to repel each other.

• The magnetic field of one magnet is stronger than the other.
