What are some common uses for
magnets? Why are they important? Use
complete sentences. At least two
sentence.
MAGNETS AND ELECTRICITY
NEXT GENERATION SCIENCE STANDARDS:
MS-PS2-3. Ask questions about
data to determine the factors
that affect the strength of
electric and magnetic forces.
OBJECTIVES
Content Objectives:
Language Objectives:
 Identify some properties of magnets.
 Define magnets, magnetic force,
magnetic poles, and magnetic field in
your science dictionary.
 Identify the causes of magnetism
 Identify types of magnets
 Build an electromagnetic device that
produces a magnetic field from an
electric current.
 Read a subtopic of a chapter and
summarize important information
and present their information.
 Complete a quick lab on
electromagnetic and answer each
question using complete sentences.
VOCABULARY:
Magnet: any material that attracts iron or objects made of
iron.
Magnetic force: when you bring two magnets together, they
exert a push or a pull on each other.
Magnetic poles: two magnets can push each other apart
because of their ends.
Magnetic field: the area surrounding a magnet where
magnetic forces can be detected.
WHAT ARE SOME PROPERTIES OF
MAGNETS?
 Many magnets are made of iron, nickel, cobalt, or mixtures of these
metals.
 Magnetic force is one of the only three forces in nature that can act at
a distance.
 Electrostatic force and gravity are also forces in nature.
 Magnetic force results from spinning electric charges in magnets.
 The force can either push the magnets apart or pull them together.
WHAT ARE SOME PROPERTIES OF
MAGNETS?
 Every magnet has a north pole and a south pole.
 If you place the north poles of two magnets together, they will repel,
or push away.
 If you place the north pole and south pole of two magnets near each
other, they will attract, or come together.
 A magnet’s magnetic field is strongest near its poles.
 The greater the distance from the poles, the weaker the magnetic
field.
EVERY DAY MAGNETS
Using a blank
piece of paper,
create
something
similar like this
and paste it into
your notebook.
Be creative.
EVERY DAY MAGNETS
Cut the
pictures and its
descriptions
and paste it
inside the
magnet
template.
EVERYDAY MAGNETS
The inside
should look
like this.
WHAT CAUSES MAGNETISM?
As an electron moves in an atom,
it makes a magnetic field.
The electron will then have a
north and a south magnetic pole.
WHAT ARE SOME TYPES OF MAGNETS?
Ferromagnetic: a material that can be
turned into a magnet
Electromagnet: an iron core wrapped
with electrical wire. When an electric
current is in the wire, a magnetic field
forms.
HOW IS EARTH LIKE A GIANT MAGNET?
 Earth has a magnetic field. Earth also has a north magnetic pole
and a south magnetic pole.
HOW IS EARTH LIKE A GIANT MAGNET?
•Scientists now think that Earth’s inner
structure produces its magnetic field. Earth’s
inner core is made of solid metals. Earth’s
outer core is made of liquid iron and nickel,
which are ferromagnetic.
•As Earth rotates, the liquid outer core moves.
Charged particles, including electrons, move
in the liquid and form a magnetic field. The
constant rotation keeps Earth magnetized.
EVERYONE SHOULD HAVE THIS PASTED IN
