Magnetic Basics
An object that exerts a magnetic force on certain metals.
What is a magnet?
This surrounds a magnet and affects other objects.
What will happen between these two magnets?
What is an attraction?
These are two invisible forces that can make objects move without touching them.
What are gravity and magnetism?
This is energy in motion.
What is kinetic energy?
Name the two magnetic poles of a magnet.
What is North and South?
When two magnetic fields interact, either one of these two things could happen.
What is attract or repel?
What force is being shown here?
What is repulsion?
Two magnets with opposite poles facing each other will...
What is attract?
This is energy stored in an object or person based on their position or shape.
What is potential energy?
True or False: Like magnetic poles attract each other.
What is false? Like poles repel each other!
Scientists use these to model invisible magnetic fields.
What are magnetic field lines?
Draw the magnetic field lines around a single bar magnet. Remember to show the directions from north to south.

What is gravity?
This type of energy can be found in the magnetic fields of a magnetic system.
The ability of a material to be attracted by a magnet and to act as a magnet.
What is magnetism?
True or False: Magnetic field lines show how magnetic forces will work between magnets.
What is True?
Draw the field lines around two magnets with opposite poles facing each other.

Which has a stronger gravitational pull: Earth or the Moon?
What is the Earth?
This phenomenon indicates that potential energy has been converted to kinetic energy.
What is motion?
What is strongest?
This phenomena is observed when two magnets have field lines that connect.
What is an attraction?
True or False: Both attraction and repulsion are taking place in the image above.
What is true?
This is the type of force a magnet's north pole exerts on another north pole.
What is a repelling force?
Energy cannot be created or destroyed, only transferred or converted. Which law is this?
What is the Law of Conservation of Energy?
