What is a magnet?
Date:____________________
A long time ago, people discovered a special type of stone. When
they hung these stones from a string, one end of
the stone pointed north. These stones were
called lodestones, or "leading stones". They could
be used to lead people in the direction they
wanted to go.
The lodestones are a type of rock called magnetite. Magnetite is
naturally magnetic. When a rock is magnetic, it is able to attract
other objects that are made from iron or steel.
Magnets
are
objects
that
attract iron or steel. There are
many types of magnets. All
magnets have a north pole and a
south pole. The poles are where
the force of the magnet is
strongest. Opposite ends of a
magnet
attract each other.
The north pole of one magnet
attracts the south pole of
another. The same ends each other. The north pole of one magnet
repels the north pole of another.
A magnet can attract objects without touching them. The space
around a magnet where its force pulls is called its magnetic field. A
magnetic field can attract an object through solids, liquids, and
gases.
