Part 1: Filling in the blanks about magnets
1.
Magnets are made from ______.
- Magnets are typically made from materials that can be magnetized, such as
iron.
-
Answer: iron
2.
They have ______ poles.
- Magnets always have two distinct poles: a north pole (N) and a south pole (S).
-
Answer: two
3.
A ______ and a ______ pole.
- The two poles of a magnet are the
north pole (N) and the
south pole (S).
-
Answer: north, south
4.
The ______ poles attract.
- Opposite poles of magnets attract each other. For example, the north pole attracts the south pole.
-
Answer: opposite
5.
The ______ poles repel.
- Same poles of magnets repel each other. For example, the north pole repels another north pole.
-
Answer: same

Part 2: Identifying magnetic objects
The task asks to determine whether certain objects are magnetic or not. Let’s analyze each object:
1.
Glasses
- Glasses are typically made of glass and plastic, which are non-magnetic materials.
-
Answer: no
2.
Shoe
- Shoes are usually made of leather, rubber, or fabric, none of which are magnetic.
-
Answer: no
3.
Paperclip
- Paperclips are often made of steel, which is a magnetic material.
-
Answer: yes
4.
T-shirt
- T-shirts are made of fabric (e.g., cotton, polyester), which is non-magnetic.
-
Answer: no
5.
Book
- Books are made of paper and possibly some metal components (like a metal clip or ring), but the book itself is not inherently magnetic.
-
Answer: no
6.
Key
- Keys are often made of metal, such as steel, which is magnetic.
-
Answer: yes
7.
Hand
- Human hands are not magnetic.
-
Answer: no
8.
Table
- Tables are typically made of wood, plastic, or metal. If the table is made of wood or plastic, it is non-magnetic. If it has a metallic component, it might be magnetic, but generally, tables are considered non-magnetic.
-
Answer: no
9.
Chair
- Chairs are usually made of wood, plastic, or metal. If the chair is made of wood or plastic, it is non-magnetic. If it has a metallic component, it might be magnetic, but generally, chairs are considered non-magnetic.
-
Answer: no

Final Answers:
1. Magnets are made from
iron.
2. They have
two poles.
3. A
north and a
south pole.
4. The
opposite poles attract.
5. The
same poles repel.
For the magnetic objects:
- Glasses:
no
- Shoe:
no
- Paperclip:
yes
- T-shirt:
no
- Book:
no
- Key:
yes
- Hand:
no
- Table:
no
- Chair:
no

\boxed{
\text{iron, two, north, south, opposite, same}
}
\]
\[
\boxed{
\text{Paperclip: yes, Key: yes}
}
\]
