Magnets repel and attract because they have opposite poles. When two magnets with different poles (one north and one south) are brought together, they attract each other, while two magnets with the same poles (both north or both south) repel each other.
Response to your inquiry in detail
Magnets have a fascinating ability to both attract and repel, and understanding why they behave this way can be quite intriguing, especially for kids. The repulsion and attraction of magnets are governed by the concept of magnetic poles.
When we talk about magnetic poles, we refer to the areas on a magnet where its magnetic force is the strongest. Every magnet has two poles: a north pole (N) and a south pole (S). According to the theory of magnetism, opposite poles attract each other, while like poles repel each other.
As mentioned in the original answer, “When two magnets with different poles (one north and one south) are brought together, they attract each other, while two magnets with the same poles (both north or both south) repel each other.” This behavior can be explained by the way magnetic fields interact.
To delve into this topic further, let’s explore some interesting facts about magnets:
-
Magnetic Field: Magnets possess a magnetic field, which is an invisible force surrounding them. This field is responsible for their attractive and repulsive behavior.
-
Magnetic Domain: Magnets are made up of tiny regions called magnetic domains. Each domain acts like a miniature magnet and contributes to the overall magnetism of the object.
-
Earth’s Magnetic Field: The Earth itself acts as a giant magnet due to its ferromagnetic core. This is what allows compasses to work, as they align themselves with the Earth’s magnetic field.
-
Magnetic Strength: The strength of a magnet is determined by its magnetic field. Powerful magnets have a stronger magnetic field than weaker ones.
-
Temporary Magnets: Some materials can be temporarily magnetized when they come into contact with a magnet. However, they lose their magnetism once the magnet is removed. This is commonly observed with objects like paper clips or needles.
-
Permanent Magnets: Other materials, such as iron, nickel, and cobalt, can retain their magnetism even after the magnet is removed. These are known as permanent magnets.
Now, to add an intriguing quote on magnets, Albert Einstein once said, “Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution.” This quote highlights the importance of curiosity and imagination in exploring phenomena like magnets and their behavior.
In order to organize the information effectively, please find below a table summarizing the main points discussed:
| Point | Description |
|---|---|
| Magnetic Poles | Every magnet has a north pole (N) and a south pole (S). Like poles repel, and opposite poles attract. |
| Magnetic Field | Magnets possess an invisible magnetic field around them, responsible for their attractive/repulsive behavior. |
| Magnetic Domain | Magnets consist of tiny magnetic domains that contribute to their overall magnetism. |
| Earth’s Magnetic Field | The Earth acts as a giant magnet, allowing compasses to align with its magnetic field. |
| Magnetic Strength | The strength of a magnet is determined by the power of its magnetic field. |
| Temporary Magnets | Some materials can be temporarily magnetized when in contact with a magnet. |
| Permanent Magnets | Materials like iron, nickel, and cobalt can retain their magnetism even when separated from a magnet. |
By exploring the concept of magnetism and its phenomena, children can develop a deeper understanding of the world around them and foster their curiosity for scientific principles.

In the video, Dr. Binocs explains what magnets are and how they work. He uses a simple experiment to demonstrate how two magnets can repel or attract each other, depending on their orientation. He also explains that the Earth has a magnetic field because of the iron and nickel in its core.

Every magnet has a north pole and a south pole. Placing two unlike poles together causes them to attract. When you try to place two like poles together (north to north or south to south), they will repel each other. The magnets are surrounded by an invisible magnetic field that contains stored-up, or potential, energy.
Magnets attract and repel each other because of the force exerted by the motion of electric charges. Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom. The magnetic field contains stored-up energy. Magnets have two poles, north and south, and unlike poles attract each other, while like poles repel each other.
Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges. Spinning like tops, the electrons circle the nucleus, or core, of an atom.
Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom. The hyperactivity of these electrons gives magnets their ability to attract and repel.

Explanation:When the like pole of two magnets comes close they repel each other because the direction of the line of force is opposite and when the opposite pol
