These poles of a
magnet repel
Like poles
Poles on a magnet
that attract
Unlike or
Opposite poles
What are the three
magnetic metals?
Iron, cobalt, and
nickel
Which pole of a
magnet is
attracted to the
North Pole of the
Earth?
North Pole
(used to be called
the “north seeking
pole”)
What rock is
magnetic?
Magnetite
(or Lodestone)
What is the
Biggest
Magnet?
The Earth
What is the area of
force around
magnet called?
The magnetic field
What do we call
all materials that
block the flow of
electricity?
insulators
What is a circuit
with a break to
stop the flow of
electricity called?
An open circuit
The part of an
atom that has a
negative
charge
the electron
A circuit that
skips a resistor
is called a:
Short Circuit
Type of electricity
caused by a build
up of electrons in
one place
Static electricity
Something that
resists or slows
down the flow of
electricity
resistor
What items are
needed to make
an
electromagnet?
battery
wires
iron bar
switch
Something that
allows you to start
and stop the flow
of electricity
through a circuit
A switch
Type of circuit
in which the
resistors are in a
single line- one
after the other
Series Circuit
A circuit with
no breaks in it
Closed circuit
What are the
names for the
three particles
in an atom?
Protons
Neutrons
Electrons
A circuit in which
the resistors are on
separate paths
Parallel circuit
A material that
carries an
electrical current
Conductor
Type of charge
an object will
have if it loses
some electrons
Positive
A device used to
prevent the flow
of too much
electricity
fuse
Or circuit
breaker
What does the
atomic number on
the periodic chart
tell us about the
atom?
The number of
protons in the nucleus
(also number of electrons
if the atom is
neutrally charged)
Type of electricity
in which charges
move in
conductors
Current
