In current electricity the negative charges have a continuous flow through a material. True or False?
True
God created the earth
with a ___________ ____________.
The ___________ ___________ is the area around a magnet where the force of the magnet can act.
magnetic field
An object that attracts certain metals is called a ___________________.
magnet
A magnet's magnetism is strongest at the ______________.
poles
All matter is made up of tiny particles that have electric charges. The tiny particles are called __________.
atoms

True
In the ___________________, God created the heavens and the earth. Genesis __:__
beginning, Genesis 1:1
A magnet does not need to touch a metal object in order for the magnet to move the object because of the magnet's _______________ field.
magnetic
A magnet that forms when electric current flows through a wire that is wrapped around a piece of metal is called an ___________________.
electromagnet
When electric charges build up on the surface of an object, ____________________ electricity occurs. Example: rubbing a balloon on your head and having your hair stand up.
static

False, electromagnet
God has given people minds to create and problem solve. How have electromagnets helped people solve real life problems?
fire alarms keep people safe, microwaves, toasters, hair dryers, and washing machines make life easier, doorbells, tvs, and computers help with communication, MRI machines help doctors treat patients, maglev trains make transportation faster
The invisible magnetic field can be observed by sprinkling __________ filings around the magnet.
iron
A material that does not allow electricity to flow through it easily is called an __________________.
insulator
A material that allows electricity to flow through it easily is called a __________________.
conductor
A light comes on when the circuit is closed. True or False?
True
Using the Bible's teaching, why is it important for us to learn about conductors and current electricity?
God made all people in His image (Genesis 1:27). People are conductors and could get hurt if they don't know how electricity works and how to make safe choices around electricity. Examples: metal objects in electric sockets, electrical cords in water
