Permanent magnet

Imagine holding a superhero toy that has the power to stick to the fridge. Now, imagine this toy magically stays stuck to the fridge even after you let go of it. This is how a permanent magnet works.

A permanent magnet is a special type of material, like a superhero toy, that has the power to attract certain things, for example iron or steel. Most of the magnets you see around you are permanent magnets. They have the ability to keep this power for a very long time, even for years, without any external help.

Now, inside a permanent magnet, there are lots of tiny little areas called "domains". These domains are like small groups of superheroes that always want to be in a specific formation, called "magnetic north" and "magnetic south". It's like they always want to stand in a specific order in line. And if anything moves them out of line, they make sure they go back into their position.

So, when a permanent magnet touches something like paperclips or other metals, the magnets' domains pull on the metals and align them to match their own formation. This makes the more significant number of domains line up in the same direction, and thus the strong magnetic effort starts. And because the domains never get tired, the magnet always retains its superhero power, making it permanent.

In summary, permanent magnets are like superhero toys that are capable of sticking to things like the fridge. These magnets have tiny groups of superheroes inside them called "domains," which always want to stand in a particular magnet "north" and "south" position. When the magnet touches another metal, they align that metal to match the formation of the domains, creating a magnetic pull, and making it stay super strong for a very long time.
