Magnet Basics
What happens when like poles face each other?
They Repel
Name one force that works without touching.
Magnetic
What type of energy is stored in a magnet system?
Potential energy.
If you push a repelling magnet closer, are you helping or fighting the force?
Fighting (moving against it).
Finish this sentence:
Potential energy increases when…
…a magnet is moved against a magnetic force.
What happens when opposite poles face each other?
They Attract
When two magnets repel, which direction do they move?
Away from each other
Does potential energy increase or decrease when you move against a magnetic force?
Increase.
What happens to potential energy when you move attracting magnets farther apart?
It increases.
Why do repelling magnets move apart when released?
Because magnetic force pushes them away.
True or False: Magnets must touch to push or pull.
False
Which has a stronger magnetic force: magnets far apart or close together?
Close together.
Fill in the blank:
Moving a magnet ______ the force stores potential energy.
Against
Two identical carts are near a center magnet. Which cart gives more PE: the one closer or farther?
Closer (stronger force).
Explain why moving magnets closer together can store energy.
You are pushing against magnetic force, transferring energy into the magnetic field.
What is a magnetic field?
A line that connects opposite magnetic poles and represents the strength and direction of the magnetic filed.
If a magnet moves on its own, what caused it?
A magnetic force.
True or False: Repelling magnets moved closer together increases potential energy.
True.
Why does moving a magnet closer to another magnet usually store more energy?
Because the force is stronger.
Two cars move away from a center magnet. Why does the closer car gain more PE?
It experiences a stronger magnetic force.
What do magnetic field lines show?
The direction and strength of magnetic force.
Why do magnets sometimes suddenly “snap” together?
The force gets stronger as distance decreases.
Which stores MORE potential energy:
Moving a magnet slightly against force or a lot against force?
A lot against force.
In the assessment, why does moving the car closest to the magnet usually increase PE the most?
It’s working against the strongest magnetic force.
Explain how force, distance, and potential energy are connected.
As distance decreases, magnetic force increases. Moving against a stronger force transfers more energy, increasing potential energy.
