Transcript Electricity and Magnetism

Time for a little
review….
Let’s start with
vocabulary!
What type of electricity occurs
when positive and negative
charges no longer balance?
HINT! HINT! HINT!
You might get a ZAP!
STATIC
ELECTRICITY
An electric charge in motion is
called an …..?
HINT! HINT! HINT!
Think of the water in a stream.
ELECTRIC
CURRENT
In what kind of circuit can an
electric charge flow only in
ONE path?
In what kind of circuit can an
electric charge flow in TWO or
MORE paths?
SERIES CIRCUIT
PARALLEL CIRCUIT
A force that acts on moving
electric charge and magnetic
materials that are near a
magnet is called….?
HINT! HINT! HINT!
This is when you find a magnetic
field!
MAGNETISM
A coil of wire with many loops
through which an electric
current passes is called an ….?
HINT! HINT! HINT!
Just combine our two key
words!
ELECTROMAGNET
What else do we
know about
electricity and
magnetism?
Let’s find out!
A ________ has a positive
charge.
An _______ has a negative
charge.
A ________ has no charge.
PROTON
ELECTRON
NEUTRON
Opposite charges …..?
Like charges …..?
HINT! HINT! HINT!
Proton + Electron
Proton + Proton
Electron + Electron
Opposites
attract!
Like charges
repel!
Magnets have two poles.
What are they called?
HINT! HINT! HINT!
Think directions.
Where is the attraction on a
magnet the strongest?
NORTH AND
SOUTH
THE POLES!
What are the ONLY three
materials that are magnetic?
HINT! HINT! HINT!
Think Bill Nye and metals.
IRON
NICKEL
COBALT
A material or object that
allows electricity to flow
through it is called….?
Examples of these are….
CONDUCTORS
Copper
Water
Iron
A material or object which
blocks the flow of electricity is
called….?
Examples of these are….
INSULATORS
Wood
Glass
Rubber
REMEMBER!
Just because a
material is a
conductor DOES
NOT mean that it is
magnetic!
AND NOW…
Vocabulary
I
Vocabulary
II
Conductor or
Insulator?
