This document defines key terms related to magnets and magnetism. It explains that a magnet produces a magnetic field that attracts metals and can be used to stick a note to a refrigerator. Iron filings are used to observe magnetic field lines. A paper clip is a piece of bent wire used to hold paper that is easily attracted by magnets since it contains metal. Attract means a magnet pulls an object towards it, while repel means it pushes an object away. Magnetic fields are the areas around magnets that cause attraction and repulsion. Magnetic domains are regions in materials where magnetic fields of atoms are aligned. Magnetic force is the effect that causes attraction and repulsion. Magnetic poles are the strongest parts of a magnet's

1. Magnet (Noun)
An object that produces a magnetic field and
attracts metallic materials.
“Use a magnet to stick a note to the
refrigerator door.”

2. Iron filings (or Iron sand)
Small pieces of iron used to show the
direction of a magnetic field.
“Observe the shape iron filings take when
around a magnet.”

3. Paper clip (Noun)
A piece of bent wire used to hold paper
together.
“Magnets easily attract paper clips because
they are usually made of metal.”

4. Attract (Verb)
When a magnet pulls an object (usually made
of metal) towards it.
“Magnets attract any object that contains iron.”

5. Repel (Verb)
When a magnet pushes an object away from it.
“Putting the N pole of one magnet near the N
pole of another magnet will repel it.”

6. Magnetic field (Adjective+Noun)
The area around a magnet that can attract or
repel objects.
“Larger magnets have wider and more powerful
magnetic fields.”

7. Magnetic Domain (Adjective+Noun)
A magnetic domain is region in which the magnetic fields
of atoms are grouped together and aligned.
“In a magnet or a magnetized object, all magnetic
domains are aligned.”

8. Magnetic force (Adjective+Noun)
The effect that causes magnets to attract or
repel objects.
“Larger magnets have a stronger magnetic
force than smaller ones.”

9. Magnetic Pole (Adjective+Noun)
The strongest area of magnetic force in a
magnet.
“North and South magnetic poles of a magnet
attract.”

10. Independent variable (Noun)
The element of an experiment that you
change.
“Amount of water can be an independent
variable in an experiment on photosynthesis.”

11. Dependent variable (Noun)
The element of an experiment that you
measure.
“The growth of a plant measured in cm can be
a dependent variable in an experiment.”

12. Trial (Noun)
The successful completion of an
experiment’s procedure.
“Perform several trials for more accurate results.”

13. Compass with a Compass Needle (Noun)
An instrument that shows the direction of
magnetic north.
“Campers and hikers use a compass so they don’t get
lost.”

14. Scale (Noun)
An object used to determine the weight of
materials.
“Use the scale to weigh the iron sand that your magnet
picked up.”

15. Doughnut magnet

16. Red and blue horseshoe magnet

17. Grey rectangle magnet

18. Red and blue bar magnet

19. Silver sphere magnet

20. Plastic stick magnet
