Magnets and electromagnets worksheet - Free Printable

Let’s go through each question one by one and solve it step by step.

---

Question 1: Choose the correct word to complete these sentences

a. All magnets have ___ opposite poles.
→ Magnets always have two poles: North and South. So, “two” is correct.

b. Identical poles ___ each other.
→ Same poles (like North-North or South-South) push away from each other → that’s “repel”.

c. Opposite poles ___ each other.
→ North and South pull toward each other → that’s “attract”.

✔ Answers for Q1:
a. two
b. repel
c. attract

Question 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.
→ Compasses use a small magnetized “needle”.

d. The Earth has two ______, located near the geographical poles.
→ Earth acts like a big magnet with “magnetic poles”.

e. The magnetic force of an induced magnet is ______.
→ Induced magnets are temporary and weak → so “weakest” fits here.

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

g. The Earth’s core contains ______, which acts like a giant magnet.
→ Scientists believe it’s “molten iron” moving inside that creates Earth’s磁场.

h. The areas around a magnet’s poles are where the magnetic field is the ______.
→ Strongest at the poles → “strongest”.

✔ Answers for Q2:
a. permanent
b. magnetic field
c. needle
d. magnetic poles
e. weakest
f. filings
g. molten iron
h. strongest

Question 3: What is electromagnetism? Fill in the gaps

Electromagnetism is the relationship between ______ and ______.

→ Electromagnetism links electricity and magnetism. When electric current flows, it creates a magnetic field. And changing magnetic fields can create electricity.

✔ Answer:
electricity and magnetism

Question 4: Which of the following materials are magnetic?

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

Magnetic materials are those attracted to magnets. Common ones: iron, nickel, cobalt, and some alloys like steel (which contains iron).

- Silver → not magnetic
- Nickel → YES, magnetic
- Copper → not magnetic
- Glass → not magnetic
- Steel → YES, because it has iron
- Iron → YES, very magnetic

✔ Magnetic materials: nickel, steel, iron
