Let’s go step by step to solve each part of the worksheet.
---
Part A: Choose the correct word to complete the statements.
1.
All magnets have _______________ opposite poles.
→ Every magnet has two ends: a north pole and a south pole. These are called “opposite” poles. So, all magnets have
two opposite poles.
✔ Answer:
two
2.
Same poles of two magnets will _______________ each other.
→ If you put two north poles together (or two south poles), they push away from each other. That’s called repelling.
✔ Answer:
repel
3.
Opposite poles of two magnets will _______________ each other.
→ North and south poles attract — they pull toward each other.
✔ Answer:
attract
4.
The area around a magnet is called _______________.
→ This invisible space where the magnet can affect things (like iron) is called its magnetic field.
✔ Answer:
magnetic field
5.
A magnet that is powered by electricity is called a/an _______________.
→ When we use electric current to make something magnetic, it’s called an electromagnet.
✔ Answer:
electromagnet

Part B: True or False
6.
An electromagnet is an example of a permanent magnet.
→ FALSE. Electromagnets only work when electricity flows through them. Permanent magnets stay magnetic all the time without needing power.
✔ Answer:
False
7.
You can increase the power of an electromagnet by adding more power source.
→ TRUE. More voltage or current (from batteries or power supply) makes the electromagnet stronger. Also, more coils help too — but here it says “more power source,” which means more electricity → stronger magnet.
✔ Answer:
True
8.
Cotton and paper are magnetic.
→ FALSE. Only materials like iron, nickel, and cobalt are attracted to magnets. Cotton and paper are not magnetic at all.
✔ Answer:
False
9.
Coiling the wires more will decrease the power of electromagnets.
→ FALSE. Actually, coiling the wire MORE times around the core makes the electromagnet STRONGER. More loops = stronger magnetic field.
✔ Answer:
False
10.
Electromagnets can be turned on and off.
→ TRUE. That’s one of their best features! Just turn the electricity on or off — no need to remove anything.
✔ Answer:
True
