ClassX Video Lessons Youtube Channel Next Generation Science Making a Magnet Using the Stroke Method
Have you ever wondered how to turn a regular metal nail into a magnet? It’s a fun and simple experiment you can try at home! Let’s learn how to do it using a bar magnet and a few metal staples.
First, let’s see what happens when we bring the metal nail close to the staples. You’ll notice that nothing happens because the nail isn’t a magnet yet.
To make the nail magnetic, take one end of the bar magnet and rub it along the nail in one direction. Do this several times, always moving the magnet in the same direction. This is called the “stroke method.”
Now, let’s test if our nail has become a magnet. Bring the nail close to the metal staples again. This time, you’ll see that some of the staples stick to the nail! This means the nail has been magnetized.
Want to make your magnetized nail even stronger? Try experimenting with different techniques. For example, you could stroke the nail more times or use a stronger magnet. See what works best!
Have fun exploring the world of magnets, and remember, science is all about curiosity and discovery!
Magnet Hunt: Go on a magnet hunt around your house! Find different objects and test if they are magnetic by seeing if they stick to your magnetized nail. Make a list of the items that are magnetic and those that are not. Discuss with your family why some objects are attracted to magnets while others are not.
Magnet Art: Create a piece of art using your magnetized nail. Gather some iron filings or small metal shavings (with adult supervision) and place them on a piece of paper. Use your magnetized nail to move the filings around and create interesting patterns or pictures. Share your artwork with your class or family and explain how the magnet helped you create it.
Question Time: Think about these questions and discuss them with a friend or family member: Why do you think the nail becomes a magnet when you rub it with the bar magnet? How do you think the magnetism in the nail works? Can you think of other ways to make a magnet? Write down your thoughts and ideas!

In this video, we will explore how to use a bar magnet to magnetize a metal nail. We have a bar magnet, a metal nail, and some metal staples.
First, let’s observe that the nail is not magnetic when held near the staples. To magnetize the nail, we can stroke one of the magnet’s poles along the nail in the same direction, like this.
After magnetizing, when we bring the nail near the staples, we can see that some of the staples are now attracted to the nail. This indicates that the nail has been successfully magnetized.
What could you do to increase the strength of the magnetized nail? We encourage you to create your own investigation to find out!
