Electricity
What type of electricity is naturally occuring?
Static electricity
What are the parts of a simple circuit?
Power source, wires, load and switch (optional)
What are conductors?
Materials that allow electricity to flow
Whare are 2 types of magnets?
Permanent magnets and electromagnets
What is a magnetic field?
The invisible area around a magnet where it can attract or repel objects
What type of electricity is human harnessed?
Current electricity
What is a power source?
usually a battery that provides energy by converting chemical energy
Give an example of a conductor
metal paperclips, desk legs, aluminum foil
Which type of magnet is always magnetic (cannot be turned off)?
A permanent magnet
Can magnetic fields pass through materials?
Yes, but their strength may decrease depending on the thickness and type of material
What causes static electricity?
Buildup of electric charges. Cannot be controlled by humans
what are wires?
They carry electrical energy from the power source to the lightbulb (load)
What are insulators?
Materials that block electricity
Does a permanent magnet require electricity?
No
How could you test which materials magnets interact through?
What is current electricity?
A steady flow of electrons through a conductor. It can be turned on and off and directed through circuits
What is the load?
A device like a light bulb that uses electricity
Give an example of an insulator
rubber, wood, plastic, glass
When is a permanent magnet used?
When a constant magnetic field is needed
What happens to a magnetic field when it passes through thicker materials?
It weakens
Give some examples of static electricity.
lightning, rubbing a balloon on your hair, socks sticking together after drying, eels and fireflies due to their electrical charges within
What is the switch (an optional part)?
Opens and closes the circuit to control the flow of electricity
What type of magnet is created by electricity flowing through a wire?
electromagnet. The strength can be adjusted by increasing the number of coils.
How is current electricity used?
to power devices like lamps, computers, and appliances
True or false: A closed circuit means electricity flows through a complete path.
True.
An open circuit is one in which electricity cannot flow since the path is broken.
Where are electromagnets used?
devices like doorbells, speakers and motors
