Exploring Magnets
Introduction
Ancient History
Magnets have been 
used for centuries, with 
sailors in ancient times 
relying on magnetic 
compasses to navigate 
their ships.
Natural & Artificial
Magnets can be natural, 
such as lodestones, or 
artificial, made from 
materials like iron or 
other metals.
Everyday Use
T oday, we find magnets in many everyday items, 
including pencil boxes, toys, and even in school supplies. 
They come in different shapes and sizes, serving various 
purposes in our daily lives.

Magnetic and Non-magnetic Materials
Magnetic Materials
Materials attracted to magnets include iron, 
nickel, and cobalt. These metals respond to 
magnetic fields and are pulled toward magnets.
Non-Magnetic Materials
Materials not attracted to magnets include wood, 
plastic, rubber, and glass. These substances don't 
respond to magnetic fields and remain unaffected 
by magnets.
Which geometry box tools are non-metal? How do they differ from metal tools? How are magnets useful in 
daily life? Can you name examples of magnet applications?

Poles of a Magnet
Two Poles
Every magnet has two poles: a 
North Pole and a South Pole. The 
magnetic force is strongest at 
these poles.
Iron Filings Test
If you were to sprinkle iron 
filings around a bar magnet, you 
would notice that the filings 
gather more densely at the ends 
of the magnet, indicating the 
location of the poles.
Inseparable Poles
It is impossible to get a magnet 
with only one pole. Even if you 
break a magnet into smaller 
pieces, each piece will still have 
both a North and a South pole.
Why do you think the iron filings stick more to the ends (poles) of the magnet rather than the middle? Why 
do you think it's impossible to find a magnet with just one pole?

Finding Directions
Freely Suspended Magnet
A freely suspended magnet aligns in the north-south direction 
due to Earth's magnetic field.
North and South Poles
The end pointing north is called the North-seeking pole, while 
the end pointing south is the South-seeking pole.
Suspending the Magnet
Hang a bar magnet from a thread so it can rotate freely 
without obstruction.
Alignment
The magnet will rest in the north-south direction. 
When disturbed, it will return to this alignment.
