Educational worksheet about magnets with true/false questions and magnet shape identification.

Section 1: True or False

#### Instructions: Write 'T' on the line if the statement is TRUE and 'F' on the line if the statement is false.

1. A magnet produces a magnetic field.
- Answer: T
- Explanation: Magnets generate a magnetic field around them, which is responsible for their ability to attract or repel other magnetic materials.

2. Magnets can attract nickel, silver, and cobalt.
- Answer: F
- Explanation: Magnets can attract ferromagnetic materials such as iron, nickel, and cobalt. However, silver is not ferromagnetic and is not attracted by magnets.

3. Magnets normally have a north-seeking pole and a south-seeking pole.
- Answer: T
- Explanation: Every magnet has two poles: a north pole (N) and a south pole (S). The north pole of a magnet points toward Earth's geographic North Pole (which is actually a magnetic south pole), and the south pole points toward Earth's geographic South Pole (which is a magnetic north pole).

4. Unlike poles do not attract.
- Answer: F
- Explanation: Unlike poles (e.g., north and south) attract each other. This is a fundamental property of magnets.

5. Like poles do not attract.
- Answer: T
- Explanation: Like poles (e.g., north-north or south-south) repel each other. They do not attract.

6. If the north pole is placed with the north pole of another magnet, they will attract.
- Answer: F
- Explanation: If the north pole of one magnet is placed near the north pole of another magnet, they will repel each other because like poles repel.

7. Magnets suspended on a string will always lie in an east-west direction.
- Answer: F
- Explanation: When a magnet is suspended freely (e.g., on a string), it aligns itself along the Earth's magnetic field, which is approximately north-south, not east-west.

8. Plastic cannot be attracted by a magnet.
- Answer: T
- Explanation: Plastic is not a magnetic material and is not attracted by magnets. It is non-magnetic.

9. Staples can be attracted by magnets.
- Answer: T
- Explanation: Staples are typically made of steel, which contains iron. Since iron is ferromagnetic, staples can be attracted by magnets.

10. Watches made of pure silver and gold will not attract a magnet.
- Answer: T
- Explanation: Silver and gold are not ferromagnetic metals. They are not attracted by magnets.

Section 2: Label the shapes of the magnets using their correct name.

#### Instructions: Identify the shape of each magnet based on its appearance.

1. First Image (Circular with a hole)
- Label: Ring Magnet
- Explanation: This magnet is circular with a central hole, making it a ring magnet. Ring magnets are often used in motors and generators.

2. Second Image (Rectangular bar with red and blue ends)
- Label: Bar Magnet
- Explanation: This magnet is a long, rectangular bar with distinct north and south poles at its ends. Bar magnets are commonly used in experiments and demonstrations.

3. Third Image (U-shaped with red and blue ends)
- Label: Horseshoe Magnet
- Explanation: This magnet is U-shaped, with the poles located at the ends of the "U." Horseshoe magnets are designed to concentrate the magnetic field between the poles.

4. Fourth Image (Two rectangular bars side by side)
- Label: Double Bar Magnet
- Explanation: This magnet consists of two rectangular bars placed side by side, each with its own north and south poles. Double bar magnets are often used in applications requiring strong, localized magnetic fields.

5. Fifth Image (Irregular rock-like shape with metal filings)
- Label: Natural Magnet (Magnetite)
- Explanation: This image shows a natural magnet, likely magnetite, which is a naturally occurring magnetic mineral. The filings indicate the presence of a magnetic field.
