Exploring Magnets — A Mystery at Sea
Meet Reshma, a curious girl from Kerala. For her school project she was writing a story about brave sailors who crossed the oceans hundreds of years ago. At night, the sailors looked up at the stars to find out which way their ship should go. But one night, a terrible storm came. Thick clouds covered the sky — no stars could be seen!
How did the sailors find their way home? Reshma's grandfather smiled and whispered one word: "the magnetic compass". A tiny needle inside a small round box always pointed north, no matter how the ship rocked. That clever little magnet saved many lives.
A tiny magnet, a big journey: Even today, the same idea helps aeroplanes, trekkers, boy scouts and mountaineers find their way. You may have seen magnets in your pencil box flap, fridge door, purse clasp, or the whiteboard at school — but the compass was perhaps the first great gift of the magnet to humankind.
4.1 Magnetic and Non-Magnetic Materials
Have you ever held a fridge magnet near different objects at home? It sticks tight to the steel fridge door but slips off the wooden table. Why? Because only some materials feel a magnet's pull. Let's find out which.
Activity 4.1 — Attracted or Not? L3 Apply
You need: A small bar magnet, and these everyday objects — a paper clip, a sharpened pencil, an iron nail, a plastic ruler, a piece of aluminium foil, a copper wire, a small coin, a safety pin, a rubber band, a piece of chalk.
- Keep the objects on a table.
- Slowly bring the magnet close to each item.
- Write down in Table 4.1 whether the magnet pulls it or not.
Predict: Which of these do you think the magnet will pull? Write your guess before you try.
| Object | Material | Attracted by magnet? |
|---|---|---|
| Paper clip | Iron/steel | Yes |
| Sharpened pencil | Wood + graphite | No |
| Iron nail | Iron | Yes |
| Plastic ruler | Plastic | No |
| Aluminium foil | Aluminium | No |
| Copper wire | Copper | No |
| Rupee coin | Steel (newer coins) | Usually yes |
| Safety pin | Steel | Yes |
| Rubber band | Rubber | No |
| Chalk piece | Calcium compound | No |
Objects made of iron or steel (paper clip, nail, safety pin, new coins) get pulled by the magnet. Wood, plastic, rubber, paper, aluminium, copper and chalk are not attracted — they simply stay still.
What We Learn
Magnetic Materials
Materials that a magnet pulls towards itself — mainly iron, nickel, cobalt and steel (an alloy of iron).
Non-Magnetic Materials
Materials that a magnet does not pull — like wood, plastic, rubber, paper, glass, aluminium, copper, gold, silver.
Careful! Not every shiny metal is magnetic. Aluminium, copper, gold and silver are metals, but a magnet does not pull them. Only iron, nickel and cobalt (and alloys containing them) are truly magnetic.
The first magnet — Lodestone: Long before magnets were made in factories, people in ancient Greece found dark stones in a place called Magnesia that strangely pulled iron bits towards them. These natural magnets are called lodestones, and the mineral inside them is magnetite (Fe3O4).

4.2 Poles of a Magnet
A magnet is not equally strong everywhere on its body. Try this neat experiment!
Activity 4.2 — Where the Pull is Strongest L3 Apply
You need: A bar magnet, a plate of fine iron filings (or scrape a few from an iron nail with a file).
- Dip the bar magnet into the heap of iron filings.
- Lift the magnet gently and look at where the filings cling.
Predict: Where do you think most iron filings will stick — at the ends or in the middle?
More filings cling at the two ends of the magnet. Very few (or none) stick to the middle part. The two ends pull the strongest — these are called the poles of the magnet.
Poles of a magnet: The two regions near the ends of a magnet where its pulling power is the greatest. Every magnet has two poles — the North Pole (N) and the South Pole (S).
Can a Single Pole Exist Alone?
What if we cut a bar magnet into two? Do we get one N-magnet and one S-magnet? Surprisingly, no! Each piece immediately becomes a brand-new small magnet with both N and S poles. Break it again — still both poles. Poles always come in pairs.
Activity 4.3 — Which Way Does a Magnet Rest? L3 Apply
You need: A bar magnet, a length of thread, OR a small piece of cork and a bowl of still water.
- Tie the thread to the middle of the bar magnet and let it hang freely (far from iron objects!).
- OR, float the magnet on the cork in the bowl of water.
- Wait until it stops moving. Mark the direction it points.
- Give it a gentle push and let it settle again. What do you notice?
No matter how you turn it, the magnet always settles in the North–South direction. The end that points to the geographic north is called the North-seeking pole (or simply North Pole, N). The other end is the South Pole (S). This is exactly how the old sailors' compass worked!
4.3 Finding Directions Using a Magnet
Why does a freely hanging magnet always line up north–south? The surprising answer — the Earth itself behaves like a giant magnet! This giant Earth-magnet gently pulls every small magnet (including the needle inside a compass) into line.
A compass is simply a tiny bar magnet in the shape of a needle, balanced on a sharp pointed pin (called a pivot) so it can spin freely. A dial below the needle shows the eight directions — N, E, S, W, NE, SE, SW, NW.
Activity 4.4 — Using a Compass L3 Apply
- Place the compass on a flat table, away from iron objects or mobile phones.
- Wait a few seconds till the needle stops wobbling.
- Gently rotate the compass body (NOT the needle!) till the 'N' on the dial sits below the red end of the needle.
- Now the other letters on the dial show the correct directions.
Once aligned, whichever way you face, you can tell which direction lies to your left, right, front and back. Hikers, pilots and ship captains use compasses just like this.
Competency-Based Questions
Reshma brought to her classroom a small bar magnet, a box of pins, pencils, aluminium foil strips, plastic combs, a cork, a bowl of water and a thread. She wanted to test her friends on what they had learnt about magnets.
Q1. Which pair of materials will BOTH be attracted to the bar magnet? L2
Answer: C. Pins and iron nails are made of iron/steel — both magnetic. Aluminium, wood, plastic, cork and thread are non-magnetic.
Q2. Reshma hangs the bar magnet with the thread. After a minute it stops. What will be its final position? L2
Answer: B. A freely suspended magnet always rests in the North-South direction because Earth itself is a huge magnet.
Q3. Reshma carefully cuts her bar magnet in half. What does she get? L3
Answer: B. Magnetic poles always come in pairs. Each new piece becomes a full magnet with both an N pole and an S pole.
Q4. State TRUE or FALSE: All metals are attracted to a magnet. L1
False. Only iron, nickel, cobalt and their alloys (like steel) are magnetic. Aluminium, copper, gold and silver are metals but are NOT attracted by a magnet.
Q5. Reshma dips her bar magnet into a dish of iron filings and lifts it up. Describe what she will see and explain why. L4
She will see heavy clumps of iron filings stuck to the two ends of the magnet and very few in the middle. This is because a magnet's pulling strength is greatest at its poles (the ends) and nearly zero in the central region.
Assertion – Reason
Assertion (A): A freely hanging bar magnet always points in the North-South direction.
Reason (R): The Earth itself acts like a giant magnet.
Answer: A. Earth's magnetism pulls small magnets into line along its north-south axis — so R correctly explains A.
Assertion (A): Aluminium foil is attracted by a magnet.
Reason (R): Aluminium is a metal.
Answer: D. Aluminium IS a metal (R is true) but it is NOT attracted by a magnet (A is false). Only iron, nickel and cobalt metals are magnetic.
Assertion (A): Iron filings cluster at the two ends of a bar magnet.
Reason (R): The pulling power of a magnet is strongest at its poles.
Answer: A. The ends ARE the poles, and poles are the strongest regions — so the filings cluster exactly there.
