Question 1.9. Nonmagnetic substances
Answer: Wood, plastic, glass, and paper
In simple words: Materials that are not attracted by a magnet at all.

Exam Tip: Non-magnetic materials do not experience any force when placed near a magnet.

Question 1.10. Name two properties of a magnet
Answer: 1. Directive property: A freely suspended magnet always aligns in the North-South direction.
2. Attractive property: A magnet attracts magnetic materials like iron towards its poles.
In simple words: Magnets point towards the earth's poles and pull iron objects toward themselves.

Exam Tip: Mention both attractive and directive properties clearly for full credit.

II) Define the following:

Question II.1. Natural magnet
Answer: A natural magnet is an ore of iron (magnetite) found in nature that possesses magnetic properties naturally without any human processing.
In simple words: Rocks that act as magnets naturally found in the earth.

Exam Tip: State that they occur naturally and are generally weak compared to artificial magnets.

Question II.2. Artificial magnet
Answer: Magnets made by humans using iron pieces or alloys in laboratories or factories are called artificial magnets.
In simple words: Man-made magnets shaped like bars, horseshoes, or cylinders.

Exam Tip: Give examples such as bar magnets, cylindrical magnets, and horseshoe magnets.

Question II.3. North pole
Answer: The pole of a freely suspended magnet that points towards the geographic North direction is called its North pole.
In simple words: The end of a magnet pointing toward the North.

Exam Tip: Often painted red or marked with the letter 'N'.

Question II.4. South pole
Answer: The pole of a freely suspended magnet that points towards the geographic South direction is called its South pole.
In simple words: The end of a magnet pointing toward the South.

Exam Tip: Often marked with the letter 'S'.

Question II.5. Magnetic substances
Answer: The materials that get strongly attracted towards a magnet are called magnetic substances, such as iron, cobalt, and nickel.
In simple words: Materials that stick to magnets.

Exam Tip: Always include examples in your definition.

Question II.6. Non magnetic substances
Answer: The materials that are not attracted by a magnet are called non-magnetic substances, such as wood, plastic, rubber, and glass.
In simple words: Materials that do not stick to magnets.

Exam Tip: Emphasize that they show no magnetic interaction.

Question II.7. Compass
Answer: A small box with a magnetic needle pivoted at the center, which rotates freely to show directions (North and South), is called a compass.
In simple words: A navigational tool with a freely rotating magnetic needle used to find directions.

Exam Tip: Mention the pivoting of the needle freely on a nail or pin.

Question II.8. Magnetic poles
Answer: The two regions near the ends of a magnet where the maximum attraction or magnetic force is concentrated are called magnetic poles.
In simple words: The regions at the ends of a magnet with the strongest pulling power.

Exam Tip: Note that magnetic strength is zero at the center and maximum at the poles.

III) Correct the following statements:

Question III.1. Magnetic strength is maximum in the middle of a bar magnet
Answer: Magnetic strength is maximum at the poles (ends) of a bar magnet.
In simple words: The strongest pulling power is at the ends, not in the middle.

Exam Tip: Highlight the corrected word by underlining or bolding it.

Question III.2. Unlike poles of a magnet repel each other
Answer: Unlike poles of a magnet attract each other.
In simple words: Opposite poles pull towards each other, while like poles push apart.

Exam Tip: Rule of magnetism: Like poles repel, unlike poles attract.

Question III.3. A pair of magnets are stored in such a way that their similar poles face each other
Answer: A pair of magnets are stored in such a way that their opposite (dissimilar) poles face each other along with a piece of wood and two soft iron keepers.
In simple words: Store magnets with opposite poles next to each other separated by wood.

Exam Tip: Proper storage prevents magnets from self-demagnetizing.

Question III.4. Magnetite is a powerful artificial magnet
Answer: Magnetite is a natural weak magnet.
In simple words: Magnetite is found in nature naturally and is not artificially manufactured.

Exam Tip: Artificial magnets are much stronger than natural magnetite rocks.

IV) Distinguish between:

Question IV.1. Natural and artificial magnets
Answer:
- Natural magnets occur naturally in the earth (e.g., Magnetite), whereas artificial magnets are manufactured by humans using iron or steel.
- Natural magnets have irregular shapes and weak magnetic strength, whereas artificial magnets can be made into various strong shapes (bar, horseshoe, cylindrical).
In simple words: Natural magnets are found in nature, while artificial magnets are made by people and are stronger.

Exam Tip: Present differences in a clear comparative point-by-point format.

Question IV.2. Magnetic and non magnetic materials
Answer:
- Magnetic materials are attracted by a magnet (e.g., iron, nickel, cobalt), whereas non-magnetic materials are not attracted by a magnet at all (e.g., wood, plastic, paper).
- Magnetic materials can be magnetized to become magnets, whereas non-magnetic materials cannot.
In simple words: Magnetic materials stick to magnets, while non-magnetic materials do not.

Exam Tip: Always provide clear examples for both categories.

Question IV.3. North pole and south pole
Answer:
- The North pole of a magnet points towards the geographic North direction when freely suspended, whereas the South pole points towards the geographic South direction.
- A North pole repels another North pole and attracts a South pole, whereas a South pole repels another South pole and attracts a North pole.
In simple words: The North pole points North and the South pole points South, and opposite poles attract.

Exam Tip: Clearly state both directional and interactive differences.

V) What happens:

Question V.1. When S pole of a magnet is brought near the South Pole of a freely suspended magnetic needle
