CHAPTER 18 M SECTION 1 Magnets and Magnetic Fields
The magnetic fields of individual atoms balance one another in most materi- als. Those materials, such as copper and aluminum, are not magnetic. In some materials, including iron, nickel, and cobalt, atoms form larger groups called magnetic domains. The magnetic fields of all the atoms in a magnetic domain line up in the same direction.
Magnetism and Magnetic Fields | Boundless Physics
A magnetic field line can never cross another field line. The magnetic field is unique at every point in space. Magnetic field lines are continuous and unbroken, forming closed loops. Magnetic field lines are defined to begin on the north pole of a magnet and terminate on the south pole.

All magnets have two magnetic poles,regions where the magnet’s force is strongest. One end of a magnet is its north pole;the other end is its south pole.The direction of magnetic force between two magnets depends on how the poles face. Like magnetic poles repel one another, and opposite magnetic poles attract one another.
