key concepts
It can attract or repel an object at a distance
What can a magnetic force do? (1)
Stored as potential energy in the magnetic field.
Where is the energy used to move a magnet against a magnetic force stored? (5)
to pull objects toward one another
what does it mean to attract?
something that can be changed and may be measured
what is a variable?
the space around a magnet in which magnetic forces can act on objects
There is a repelling force between like pole and an attracting force between opposite poles
What is there in a system of magnets? (2)
It helps scientists test and explain the relationship between force and energy.
What does making a model of a scientific system and defining its parts help with? (6)
to push objects away from each other
what does it mean to repel?
an object, diagram, or computer program that helps us understand something by making it simpler or easier to see
What is an model
to provide evidence that goes against a claim
what does it mean to refute?
Are the magnetic field lines of attracting magnets and repelling magnets same or different? (3)
Transfers more energy
Does moving a magnet against a stronger magnetic force transfer more or less energy to the magnetic field? (7)
one of the two opposite ends of a magnet
what is a magnetic pole?
a set of interacting parts forming a complex whole
what is a system?
the ability to make things move or change
what is energy?
A magnetic force converts potential energy into kinetic energy.
What can a magnetic force convert? (4)
Strong closer to a magnet
Is a magnetic force stronger or weaker closer to a magnet? (8)
to separate or set apart
what does it mean to isolate?
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 an object has because it's moving
what is kinetic energy?
a type of magnet in which the magnetic field is produced by an electric currentw
what is an electromagnet?
to move from one object to another or one place to another
what does it mean to transfer
to change from one type to another
what does it mean to convert?
the energy that is stored in an object or system
what is potential energy?
