Have you ever wondered how some things can stick to a board without glue? It’s because of something called a magnet! Let’s explore what magnets are and how they work.
Magnets are special objects that can pull certain things towards them. You might have seen magnets on your refrigerator or in your classroom. They help hold things up, like notes or pictures.
Every magnet has two ends called poles: a north pole and a south pole. These poles create an invisible force called a magnetic field. Even though we can’t see this force, it’s what makes magnets work!
The north pole of one magnet wants to connect with the south pole of another magnet. If you try to stick two north poles or two south poles together, they won’t stick. It’s like trying to push the same ends of two magnets together—they just won’t stay!
Let’s try a fun experiment! Imagine you have a horseshoe magnet and a bar magnet. If you bring the north pole of the horseshoe magnet close to the south pole of the bar magnet, they will attract each other and stick together. But if you try to connect two north poles, they will push away from each other.
Magnets are everywhere! They are even in compasses, which help us find directions by pointing to the Earth’s north and south poles. If you bring a strong magnet near a compass, it can change the direction the compass points!
Let’s play a guessing game! Which of these objects do you think are magnetic: a paper clip, a pencil, or a pair of scissors? Let’s find out!
When we tested them, the paper clip and scissors were magnetic, but the pencil was not. This means the paper clip and scissors can be pulled by a magnet, while the pencil cannot.
We’ve learned that if something is magnetic, it can be attracted to or pushed away by a magnet. Not everything is magnetic, but many metal objects are.
Isn’t it fun to learn about magnets? They are truly magical!
Magnet Hunt: Go on a magnet hunt around your home or classroom! Find different objects and test if they are magnetic by using a small magnet. Make a list of the items that stick to the magnet and those that don’t. Can you guess why some objects are magnetic and others are not? Discuss with your friends or family what materials these objects are made of.
Create a Compass: With the help of an adult, make your own simple compass using a needle, a small piece of cork, and a bowl of water. Magnetize the needle by rubbing it with a magnet, then carefully place it on the cork and float it in the water. Watch how it points north! Try bringing a magnet close to your compass and observe what happens. What do you notice about the needle’s direction?
Magnet Art: Use a magnet and some paper clips to create fun designs on a piece of paper. Move the magnet underneath the paper to make the paper clips dance and form shapes. Can you make a picture or a pattern? Share your artwork with your classmates and explain how the magnet helped you create it.

Wow, that’s pretty cool! How does it do that? The way this eraser is able to stick to the board like that is that it actually has a magnet built inside it. Pretty neat!
What is a magnet? What do we use magnets for? Magnets are all around us. These little clips have magnets on them, which allows us to hang things up. You might have magnets around your house, like those on a refrigerator or stuck to a bulletin board. Your teacher might have them in the classroom to hold things to their whiteboard, like clips, hooks, or just little dots.
All magnets are made up of two poles: a north pole and a south pole. These poles emit a magnetic field, which is basically a force that comes out of both sides of them. This force is invisible; we can’t see it with our own eyes, but it’s there. The south pole sends out a south field, and the north sends out a north field.
What does that mean for our magnets? It means that the north field and the south field are both reaching out for the other field. The north field is looking for a south field to attract to, and the south field is looking for a north field. This can be demonstrated with a horseshoe magnet and a bar magnet.
Here’s my horseshoe magnet, and you can see it’s labeled with a north pole and a south pole. This one is not labeled, but we know that our north pole wants to be attracted to the south pole of this bar magnet. Let’s find out! If I put this here, look, it’s attracted to it. So we can assume that this is the south pole of the bar magnet. If I flip it over and try to connect a north pole to a north pole, it won’t stick because the north pole is attracted to the south pole, and the south pole is attracted to the north pole.
With some magnets, the magnetic field is so strong that if I take these two magnets—one green and purple, and the other blue and yellow—and put them together, you can see that they have the same field. It’s either a north and a north or a south and a south, but there’s no way to get them to connect. If I really squeeze them together, they’ll pop apart.
Now, if I put the blue and purple magnets together, these are opposing, so it must be a north and a south, and they really want to be together. If I flip it over, now it’s the same pole, and they won’t stay together.
Magnets are found in all kinds of everyday objects, like these two compasses. These compasses use magnets to determine the north and south pole of the Earth. Watch what happens if I introduce my own magnet to disrupt that field. As I bring the magnet closer, they’re both attracted to my magnetic field. If I flip it, it’ll flip them over, and they’ll be attracted to the opposite end. As I pull it through, they follow. You can see that this magnet has a much stronger magnetic field than the Earth.
When we say something is magnetic, we mean that it will attract or pull closer to a magnet. I have some staples in my hand. Do we think these are going to be magnetic? Let’s try it out!
I laid some objects out on the table. Let’s think about which objects we think will be magnetic or will attract or repel to that magnetic field we talked about earlier. We have a brownie, some sunglasses, a paper clip, some metal scissors, a pencil, some post-it notes, and a pen.
Let’s start with the brownie first. Do we think it’s going to be magnetic? Nope, the brownie is not magnetic. Now how about the sunglasses? The sunglasses are not magnetic. How about my paper clip? Wow, did you see that? My paper clip is definitely magnetic! How about the pencil? Nope, not magnetic. Post-it notes? Not magnetic either. Let’s try the scissors. Definitely magnetic!
After looking at all these objects, what makes an object magnetic? My pen, post-it note, pencil, brownie, and sunglasses were not magnetic, but my scissors and paper clip were.
Let’s go over what we’ve learned so far about magnets. If an object reacts to a magnet or interacts with it, it’s called magnetic. If an object is magnetic, it can either attract or be pulled closer to a magnet or repel or push away from a magnet.
I’m definitely attracted to magnets—see what I did there?
