MAGNETISM AND ELECTRICITY
  1. Magnetism
    1. What is magnet?
      1. A magnet is a piece of metal that can attract other metals
        1. The magnets have two poles:north pole and south pole or positive and negative
      2. Electricity
        1. Electricity and atoms
          1. Electric current
            1. 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.
            2. Conductors and insulators
              1. Conductors
                1. Allow electricity to flow trough them.All metals are good conductors.When a material are good conductor we say it has low resistance
                2. Insulators
                  1. Do not allow any electricity pass trough them,like:rubber,plastic or glass.We say it has high resisance
                3. Electric charge
                  1. An objet that has not been charged in this way has fewer electrons so it has a psitive charge
                  2. Different types of circuits
                    1. Series circuit
                      1. Parallel circuit
