Magnets — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. If you rub a steel nail with a magnet, the nail turns into a magnet.
Rubbing lines up tiny bits inside steel so it acts like a magnet.
2. A nail that is a magnet for only a little while is a temporary magnet.
Temporary magnets lose their pull after a short time passes.
3. A magnet that keeps its pull for a long time is called permanent.
Permanent magnets hold their magnet power for many years on.
4. You must rub the nail with a magnet in only one direction.
Rubbing one way lines up the inside bits in a neat row.
5. A rubbed steel nail can pick up a paper clip.
The nail now pulls iron items, just like a real magnet.
6. A temporary magnet loses its power after some time.
Over time the tiny bits inside go back to being mixed up.
7. You cannot turn a wood block into a magnet by rubbing.
Only iron or steel can be turned into a short-time magnet.
8. If you drop a temporary magnet, it may lose its pull.
A drop or knock can jumble the inside bits and stop the pull.
9. A strong bar magnet can help a nail become a temporary magnet.
Rubbing with a strong magnet gives the nail a brief magnet power.
