Electricity and Magnetism.

Today I will be doing a blog post on what electricity is and what metals are magnetic and how magnets work.


What is electricity?
Electricity is the flow of electrons as a current.
How an electrical circuit is usually made.
The electrical componants and pieces of wire are linked together in a circuit/circular motion and electrons cannot flow through this circuit if it is either open or uncomplete.  
What is a conductor?
A conductor of electricity is a substance that allows the flow of electrons through it, for example, copper, steel and iron are all conductors.
What is a insulator?
An electrical insulator could be anything which does not allow the flow of electricity through it, here are 4 examples of insulators that does not allow electricity through it, wood, rubber, plastic and glass.
Batteries;
Two common things you would inside of a battery would be metals and a chemical paste.
Why do batteries go flat?
When the battery goes flat it is because the metal or chemical paste has run out.
What is a term to describe devices, such as light bulbs that use electricity to work?
A load is a device that uses electricity to work.
What happens to a bulb when the wire inside, burns out?
The electrons have stopped flowing and the wire begins to shut down.
What happens to a bulb when electricity flows through it?
The electrons start flowing through a tiny wire and then that wire begins to get hot and begins to glow.
