one another. Usually these objects are metals such as iron.

called a magnetic field. The larger the magnet and the closer the
object to the magnet, the greater the force of the magnetic field.
Magnetic Materials
The term magnetism is derived from Magnesia, the name of a
region in Asia Minor where lodestone, a naturally magnetic iron
ore, was found in ancient times. Iron is not the only material that is
easily magnetized when placed in a magnetic field; others include
nickel and cobalt.
Magnets can also be formed that are called electromagnets. A
simple electromagnet is formed with a battery and copper wire
coiled around a metal rod such as a nail. There is evidence that
there is an electrical basis for magnetism.

netism.htm
Magnetism is a force of attraction or replusion that acts at a
distance. It is due to a magnetic field, which is caused by moving
electrically charged particles or is inherent in magnetic objects
such as a magnet.
Although individual particles such as electrons can have magnetic
fields, larger objects such as a piece of iron can also have a
magnetic field, as a sum of the fields of its particles. If a larger
object exhibits a sufficiently great magnetic field, it is called a
magnet..
Attraction
When two magnets or magnetic objects are close to each other,
there is a force that attracts the poles together.
Magnets also strongly attract ferromagnetic materials such as iron,
nickel and cobalt.
Repulsion
When two magnetic objects have like poles facing each other, the
magnetic force pushes them apart.magnets can also weakly repel
diamagnetic materials.

Curie Temperature Tc
The Curie Temperature (Tc) is the temperature at which the
magnet will be completely demagnetized. Even though it may still
be a magnetic material, a material that has the ability to retain a
magnetic field when magnetized, it would have completely
demagnetized. It is important to note that taking a magnet to Tc
will demagnetize the magnet, but depending on the process used,
heating and cooling rates, and the environment that the magnet is
exposed to during the temperature cycle, heating a magnet to Tc
can cause structural or mechanical damage.
 Curie Temperature
o Temp at which magnet will be
completely demagnetized.
o Still will be a magnetic material that
has ability to retain a magnetic field.
