Vocabulary
To pull objects toward one another.
What is attraction?
Something can attract or repel an object at a distance.
What is a magnetic force?
An object, diagram, or computer program that helps us understand something by making it simpler to easier to see.
What is a model?
The ability to make things move or change.
What is energy?
Creating a [blank] of a magnetic system and defining its parts helps scientists test and explain the relationship between force and energy.
What does a model do?
To push objects away from each other.
What is repulsion?
In this thing, there is a repelling force between like poles and an attracting force between opposite poles.
What is a system of magnets?
A set of interacting parts forming a complex whole.
What is a system?
The energy that an object has because it is moving.
What is kinetic energy?
Moving a magnet against a stronger magnetic force transfers more of something to the magnetic field.
What is energy?
To separate or set apart.
What is isolation?
Something can convert potential energy stored in a magnetic field to kinetic energy.
What does a magnetic force do?
A line that connects opposite magnetic poles and represents the strength and direction of the magnetic field.
What is a magnetic field line?
The energy that is stored in an object or system.
What is potential energy?
Something is stronger closer to a magnet.
What is a magnetic force?
One of the two opposite ends of a magnet.
What is a magnetic pole?
The pattern of something around attracting magnets is different from the pattern of that same thing around repelling magnets.
What are magnetic field lines?
The space around a magnet in which magnetic forces can act on objects.
What is a magnetic field?
To change from one type to another.
What is a conversion?
Creating a model of something and defining its parts helps scientists test and explain the relationship between force and energy.
What is a magnetic system?
Something that can be changed and may be measured.
What is a variable?
The energy used to move something against a magnetic force is stored as potential energy in the magnetic field.
To provide evidence that goes against a claim.
What is refuting?
A type of magnet in which the magnetic field is produced by an electric current.
What is an electromagnet?
