Educational worksheet on magnets and electromagnets featuring interactive exercises for learning magnetic properties and concepts.

Let’s go through each part of the worksheet step by step, using what we know about magnets and electromagnets.

---

Part 1: Choose the correct word to complete these sentences

a. All magnets have ___ opposite poles.
→ Magnets always have two poles: North and South. So the answer is two.

b. Identical poles ___ each other.
→ Like poles (North-North or South-South) push away from each other → they repel.

c. Opposite poles ___ each other.
→ North and South pull toward each other → they attract.

✔ So Part 1 answers:
a. two
b. repel
c. attract

Part 2: Drag and drop words from the box

We’ll match each sentence with the best word from the list:

Words available:
temporary, weakest, magnetite, magnetic poles, molten iron, magnetic field, induced, needle, artificial, permanent, filings, cosmic radiation, strongest, nickel

a. A/An ___ magnet never loses its magnetism.
→ That’s a permanent magnet.

b. A/An ___ is the area around a magnet where its force has an effect.
→ That’s the magnetic field.

c. All compasses contain a magnetised ___ which points north.
→ The little moving part in a compass is called a needle.

d. The Earth has two ___, located near the geographical poles.
→ Earth’s magnetic poles are near the North and South geographic poles → magnetic poles

e. The magnetic force of an induced magnet is ___.
→ Induced magnets only act when near another magnet — their force is temporary and weak → weakest

f. Small pieces of iron, called ___ can help us see the effect of a magnetic field.
→ These are called filings — you sprinkle them to see field lines.

g. The Earth’s core contains ___, which acts like a giant magnet.
→ Earth’s core is made of hot, flowing metal — mostly molten iron

h. The areas around a magnet’s poles are where the magnetic field is the ___.
→ Magnetic fields are strongest at the poles → strongest

✔ So Part 2 answers:
a. permanent
b. magnetic field
c. needle
d. magnetic poles
e. weakest
f. filings
g. molten iron
h. strongest

Part 3: What is electromagnetism? Fill in the gaps

Electromagnetism is the relationship between ___ and ___.

→ Electromagnetism connects electricity and magnetism. When electric current flows, it creates a magnetic field.

✔ Answer: electricity and magnetism

Part 4: Which of the following materials are magnetic?

Options: silver, nickel, copper, glass, steel, iron

→ Magnetic materials are those that can be attracted to magnets or made into magnets. These are usually iron, nickel, cobalt, and some alloys like steel.

- Silver → NOT magnetic
- Nickel → YES, magnetic
- Copper → NOT magnetic
- Glass → NOT magnetic
- Steel → YES (it’s mostly iron)
- Iron → YES, very magnetic

✔ Magnetic materials: nickel, steel, iron

Final Answer:
1. a. two, b. repel, c. attract
2. a. permanent, b. magnetic field, c. needle, d. magnetic poles, e. weakest, f. filings, g. molten iron, h. strongest
3. electricity and magnetism
4. nickel, steel, iron
