
Magnetism is a force that causes attraction or
repulsion between objects.
Magnets always contain metal.
The atoms in a magnetic material, like iron or
steel, all point in the same direction.
Magnetic force can travel through many
materials, even water.



Magnets attract only certain types of materials which are:
steel, iron, cobalt, and nickel.
Every magnet has two poles.
The poles are the points where the magnetic force is
strongest.

One pole is called the north pole.

The other is the south pole.



The area around a magnet is called the magnetic field.
Magnetic fields are invisible.
A magnetic field is created by the magnetism of a
permanent magnet, or electromagnet.





There are different types of magnets.
Permanent
Temporary
Electromagnets
Magnets come in different shapes and sizes.


Electro-magnets are
temporary magnets that
are formed when electricity
flows through a coiled
wire.
Electromagnets come in all
shapes and sizes.
