Magnetic Force
What happens when opposite magnetic poles face each other?
They attract
Potential energy is:
stored energy
A variable is:
something that changes in an experiment
A magnetic field is:
the space where magnetic forces act
Energy transfer means:
energy moving from one object to another
A magnetic force becomes stronger when magnets are:
closer together
Kinetic energy is energy of:
movement
Why should scientists isolate one variable?
To make tests fair
Magnetic field lines move from:
North to South
When magnets push against each other, energy can be:
stored as potential energy
What does a magnetic field line show?
Direction and strength of force
When a ball rolls down a hill, potential energy converts into:
kinetic energy
A scientific model is used to:
represent or explain a system
When like poles face each other, magnets:
repel
Which situation shows energy converting?
A spring launching a ball
Which part of a magnet creates magnetic force?
Magnetic poles
Compressing a spring stores:
potential energy
Which example BEST isolates a variable?
Changing only the distance between magnets
Earth acts like a giant:
electromagnet
A stronger magnet usually transfers:
more energy
In a magnetic system, magnets can move objects by:
acting through a magnetic field
Energy can transfer and convert inside a:
system
In a magnet experiment, keeping all conditions the same except one helps scientists:
identify cause and effect
An electromagnet is created when:
electricity flows through a material
Which statement BEST explains energy in a magnetic system?
Magnetic systems can transfer and convert energy
