Magnetic Attraction worksheet for physical science education.

Let’s go through each question one by one, using the passage to find the answers.

Question 1: Explain the difference between a temporary magnet and a permanent magnet.

From the passage:
- A permanent magnet stays magnetic for a long time — even after you stop rubbing it with another magnet.
- A temporary magnet only acts like a magnet while something else (like electricity or being near a strong magnet) is affecting it. Once that stops, it loses its magnetism.

Example from text: An electromagnet is temporary — it only works when electric current flows through it. If you cut the wire, it stops being magnetic.

So the big difference:
→ Permanent = always magnetic (until damaged).
→ Temporary = only magnetic under certain conditions.

Question 2: Would two north poles attract each other or push away from each other?

The passage says:
> “Opposite poles attract each other... Like poles repel each other.”

North and North are *like* poles → so they repel (push away).

Same with South and South.

Only North + South attract.

Answer: They would push away from each other.

Question 3: What is different about an electromagnet?

From the passage:
- It’s made by wrapping wire around iron and connecting it to a battery.
- It becomes magnetic ONLY when electric current flows.
- You can turn it on/off by switching the current.
- You can make it stronger by adding more loops of wire or using a stronger battery.
- It’s temporary — not permanent.

So what’s different?
→ It needs electricity to work.
→ You can control it (turn on/off, change strength).
→ It’s not naturally magnetic — it’s created by humans using circuits.

Question 4: What do we use electromagnets for?

Passage lists many uses:
- Lift heavy metal objects (like in junkyards with cranes).
- Used in speakers, telephones, doorbells.
- Help convert electrical energy to sound or motion.

So real-world uses:
→ Cranes lifting scrap metal.
→ Making sounds in speakers/phones.
→ Ringing doorbells.

Question 5: What does attract mean when speaking about magnets?

In magnet talk, “attract” means:
→ Two things pull toward each other.

Like how a fridge magnet sticks to the fridge — that’s attraction.

Opposite poles (N-S) attract → they come together.

It’s the opposite of “repel,” which means push apart.

Final Answer:

1. A permanent magnet stays magnetic all the time; a temporary magnet only acts magnetic under certain conditions (like when electricity is flowing or near a strong magnet).
2. Two north poles would push away from each other.
3. An electromagnet is different because it only works when electric current flows through it — you can turn it on/off and adjust its strength.
4. We use electromagnets to lift heavy metal objects, in speakers, telephones, and doorbells.
5. “Attract” means to pull toward each other — like opposite magnet poles coming together.
