If you cut a permanent magnet into four pieces, you will have _____ (Mark the one best answer.)
A four temporary magnets
B four smaller permanent magnets
C two north poles and two south poles
D four objects that are no longer magnets
A paperclip moves toward a magnet when the two objects are about 2cm apart. Is this evidence that a magnet has an invisible force?
Yes
No
Sometimes you cannot push two magnets together to make them touch. Is this evidence that a magnet has an invisible force?
Yes
No
_ A magnet is placed on an aluminum pan; when you hold the magnet only, the pan falls to the floor. Is this evidence that a magnet has an invisible force?
Yes
No
Iron filings on a plate move into a distinct pattern when gently shaken above a magnet. Is this evidence that a magnet has an invisible force?
Yes
No

People often stick notes and other objects to refrigerator doors, using magnets. A student tried to do this, but the object he wanted to stick to the refrigerator fell to the floor.
What could the reasons be?
The refrigerator door is made of steel (that contains iron).
The refrigerator door is made of aluminum (not a magnetic material).
The object is too thick.
The magnet is too weak.
The object is too light.
Two magnets can attract or repel.
True
False
A magnet has a north pole or a south pole, but not both.
True
False
A magnet has an invisible magnetic field extending from its poles.
True
False
When we increased the number of magnets in our experiment, what happened to the strength of our magnetic field?
It increased.
It decreased.
Identify the difference between a temporary magnet and a permanent magnet.
A temporary magnet retains its magnetism indefinitely, while a permanent magnet loses its magnetism quickly.
A temporary magnet loses its magnetism quickly, while a permanent magnet retains its magnetism indefinitely.
Both temporary and permanent magnets retain their magnetism indefinitely.
Both temporary and permanent magnets lose their magnetism quickly.
A student has a magnet and a paper clip.
Trial 1: She holds the magnet 2 cm away from the paper clip and watches the paper clip jump to the magnet.
Trial 2: She holds the magnet 10 cm away from the paper clip but the paper clip does not move.
What can be inferred about the magnetic field strength at different distances?
The magnetic field is stronger at 2 cm than at 10 cm.
The magnetic field is equally strong at 2 cm and 10 cm.
The magnetic field is stronger at 10 cm than at 2 cm.
The magnetic field does not affect the paper clip at any distance.
