Chapter 10 Magnets Notes
... If divided, each part of a magnet has both north and south poles; we never see an unpaired north or south pole. When near each other, magnets exert magnetic forces on each other. The forces between magnets depend on the alignment of the poles; two unlike poles will attract each other and two like ...

Magnetic Forces
... Earth's base magnetic field is similar to that of a giant bar magnet. The solar wind warps this base field into a slightly different shape. However, in either case, Earth's magnetic field lines come together at the planet's poles... which is why compasses work, and is also why the aurora are most f ...
