How are the magnetic domains of a magnet different from the domains of an ordinary piece of metal?

• In a magnet, the domains all point in the same direction; in an ordinary piece of metal, they're all jumbled up.

• In a magnet, the domains all point toward the north pole; in an ordinary piece of metal, they all point to the south pole.

• In a magnet, the domains are very strong; in an ordinary piece of metal, they're all very weak.

• A magnet contains magnetic domains; an ordinary piece of metal does not

What can you infer about magnetic domains from the fact that they are arrangements of atoms?

• The individual domains are extremely small

• The individual domains are extremely large

• The individual domains attract one another

• The individual domains repel one another
