2. Producing electric current
By moving a coil of wire in a magnetic field, electricity Is produced from the wire
Stronger magnets will produce a stronger electrical current
Adding terns will also increase the electric current produced

3. Electricity It is the flow of electrons
Also is a form of energy called electrical energy
Atoms are made of three parts
-neutron
-proton
-electron

4. Static electricity Positive charges are marked with a +
Negative charges are marked with a –
Most mater is neutral

5. Electric current It is the continuous flow of negative charges
Electric circuit is the path on which negative charges flow
A switch is a device that opens and closes a circuit

6. Series and parallel circuits
A series circuit is a circuit with one path to flow on
A parallel circuit is a circuit that has more than one path to flow on

7. Magnetism It is a magnet’s property of attracting materials
Opposite poles attract and like poles repeal
The north and south pole are seeking poles of a magnet

8. Two types of magnets Iron
Temporary magnets are magnets that do not keep their magnetism for very long
Permanent magnets are magnets that keep their magnetism for a long time
Iron

9. A magnetic field is a space in which the force of a magnet can act
The earth is a giant magnet
A lodestone is a naturally magnetic rock found on or near the earth’s surface
Force fields
The lines of force is the diagram of the magnetic field of a magnet

10. Producing electric current
A generator is a device that changes motion energy to electrical energy

11. Electric magnets
A electromagnet is a magnet made when electric charges move through a coil of wires wrapped around an iron core
It can be turned on and off
Cranes, seprate different metals, computers, alarm bell, and electric motors have many uses

12. More about force fields
A compass is a magnetized needle that is allowed to swing freely
The needle is attracted to the earth’s magnetic north pole
It is used to find direction

13. Electric safety Don’t use appliances with exposed cords
Never stick your finger or any other object near or in an electric socket
Don’t overload circuits
Stay away from high voltage areas
Never touch an appliance when your wet
