Magnetic Poles

Magnets have two kinds of poles -- somewhat like the two kinds of electric charges.

Like poles repel each other.

Unlike poles attract each other.

Unlike electric charges, the magnetic poles can not be isolated.

If a magnet is broken into two pieces, each piece will still have two poles.
