Magnetic Basics
This word describes what happens when a magnet pulls an object toward it.
attract
These types of magnetic poles attract each other.
opposite poles
A diagram shows magnetic field lines close together near a magnet. What does this tell you about the magnetic force in that area?
magnetic force is stronger in that area.
A magnet starts moving toward another magnet without being touched. What type of energy is increasing as it moves?
Why do scientists define the parts of a magnetic system before testing it?
to understand how the parts interact and affect force and energy
This word describes what happens when two magnets push away from each other.
repel
These types of magnetic poles repel each other.
like poles
Two magnets are attracting. How would the magnetic field lines between them be arranged?
the field lines connect and run smoothly from one magnet to the other
A student pushes two repelling magnets closer together and then holds them still. Where is the energy stored and what type of energy is present?
A student changes both magnet strength and distance in one test. Why is this a problem?
it does not isolate variables, making results unclear
This part of a magnet can be north or south and affects how magnets interact.
magnetic pole
If two north poles are pushed together, the force between them is this.
repulsion/repelling force
Two magnets are repelling. What pattern would you expect the magnetic field lines to show between them?
the field lines curve away from each other and do not connect/interact
What energy conversion occurs when a magnet is released and snaps away from another magnet?
potential energy converts into kinetic energy
How does isolating one variable help scientists draw stronger conclusions about magnetic force?
it shows which factor caused the change
A magnetic force can act on objects even when they are not doing this.
touching/interacting
The force between magnets changes depending on this factor related to position.
distance from the magnet
A model shows evenly spaced magnetic field lines. What claim about magnetic force strength could be refuted using this model?
the claim that the force is stronger in one area than another
Why does pushing magnets closer together against a strong magnetic force require more energy than against a weak force?
because more energy is transferred into the magnetic field as potential energy
A model predicts that magnetic force increases as magnets get closer. What type of evidence could support this claim?
observations or measurements showing increased motion or resistance
This term describes a group of interacting parts working together, like two magnets affecting each other.
system
Predict what will happen when a south pole is brought near a north pole and explain why.
The magnets will attract (opposites attract).
Why are magnetic field line models useful even though the field itself cannot be seen?
they help visualize and explain how magnetic forces act at a distance and compare strength
How does distance from a magnet affect energy stored in a magnetic system?
A closer distance increases magnetic force and stores more potential energy
Explain how a model of a magnetic system can be used to test, support, or refute claims about energy transfer.
models allow scientists to predict outcomes, compare evidence, and evaluate claims about force and energy
