MAGNETISM AND ELECTRICITY
- Magnetism
- What is magnet?
- A magnet is
a piece of
metal that
can attract
other metals
- The magnets
have two
poles:north
pole and south
pole or
positive and
negative
- A magnet is
a piece of
metal that
can attract
other metals
- What is magnet?
- Electricity
- Electricity and atoms
- Electric current
- Electric
current is the
movement of
electrons.An
electic
current only
moves in a
closed circuit
or a
completed
circuit.A
switch is a
device that
opens or
closes a
circuit.

- Conductors and insulators
- Conductors
- Allow electricity
to flow trough
them.All metals
are good
conductors.When
a material are
good
conductor we say
it has low
resistance
- Allow electricity
to flow trough
them.All metals
are good
conductors.When
a material are
good
conductor we say
it has low
resistance
- Insulators
- Do not allow any
electricity pass trough
them,like:rubber,plastic
or glass.We say it has
high resisance
- Do not allow any
electricity pass trough
them,like:rubber,plastic
or glass.We say it has
high resisance
- Conductors
- Electric charge
- An objet
that has
not been
charged
in this
way has
fewer
electrons
so it has
a psitive
charge
- An objet
that has
not been
charged
in this
way has
fewer
electrons
so it has
a psitive
charge
- Different types of circuits
- Series circuit
- Parallel circuit
- Series circuit
- Electricity and atoms
