The magnetic force occurs between magnets and between magnets and some metals. Magnets have two poles called north and south that attract different poles but repel similar poles. Magnetism is caused by the movement of electric charges like electrons in atoms. Without magnetism, we would not have electricity or electric motors, and many modern technologies like phones, computers, speakers, and earphones would not exist.

1. FORCES THAT AFFECT US
The MAGNETIC Force

2. MAGNETIC FORCE – WHAT IS IT?
• The Magnetic Force
happens between
magnets,
• Also between one
magnet and some kinds
of metal.

3. 2 MAGNET WORDS
North Pole: The end of a magnet that is
attracted to the NORTH POLE of the earth.
Ferromagnetic: A metal that attracts to
magnets strongly, like Iro

4. MAGNETS HAVE 2 SIDES
Magnets have 2 different
sides, called POLES.
The are named NORTH
and SOUTH.
If you put different poles
together, they will attract
But similar poles will repel.

5. ELECTRICITY CAUSES MAGNETISM
Magnetism is caused by
moving electric charges, like
when electricity goes through
a wire.
Real magnets
are caused by
the electrons
moving in the
atoms.

6. EXAMPLES OF MAGNETIC FORCE
1. A motor uses electricity and magnets to
make it turn.
2. Speakers have magnets inside of them to
make sound. The electricity in the speaker
wire makes the magnets move and create
sound.
3. Those things you stick on your refrigerator
are all magnets which are attracted to metal

7. A WORLD WITHOUT MAGNETISM
All generators and motors use magnets.
Without the magnetic force, we wouldn’t
have any electricity or any electric motors at
all.
You wouldn’t have cell phones, or computer
disks, or speakers or earphones, since they
all use magnets.
That would be a very different world!
