THE FIRST THINGS
YOU SHOULD KNOW
ABOUT MAGNETS
AND
ELECTROMAGNETIS
The first thing that you should
know
is
that
we
use
M.
magnetism in our everyday life such as turning on a
light or using the car.
Electromagnetism is one of the factors that help us
get and use Electricity.
Some more examples on the items which we use
magnets and magnetism are Fridges , microwaves,
cars, computers, and our cell phones.

THE DOMAIN THEORY
OF MAGNETISM
The domain theory is a theory about magnetism
forces and it's properties. The theory states that a
magnet is made up of atoms while magnetic forces
happen as a result of these atoms parallel to face the
same direction. The theory is exists to explain where
magnetic forces come from in a magnet.
THE FACTORS TO
STRENGTHEN OR
WEAKEN A
ELECTROMAGNET
There are three factors
either strengthen or weaken a
(THEtoMAGNETIC
electromagnet, thanks to these three factors we can now
FIELD).
control electromagnets.
1: If you add a iron core to a electromagnet you could
strengthen the power.
2: The amount of coils, by using coils you could either
increase or decrease the power of a electromagnet.
3: The main way to control a electromagnet is to
weaken or strengthen the power of the electric current.
MAKING A ELECTRIC
MOTOR!
You can make a electric generator to see how the three factors which
weaken or strengthen a electromagnet actually effect the power of
the electromagnet.
At the end of the experiment the experiment should be successful
and you can see how the main factor which changes the power is the
strength of the electric power. You will probably not use a Iron core
so you cannot see the effect however, you could manage to see how
the amount of coils affected the overall power.

DID YOU KNOW
Did you know that one of the reasons of how birds
know where is south and north to know where to
migrate to is because they practically have a compass
in there beak.
The modern compass today started with the
knowledge of humans of the earth (rocks)!
