Permanent magnets are things that stay magnetized forever, just like your favorite toy stays strong even after you play with it all day.
Imagine you have a special kind of brick, not the ones you stack to build a wall, but one that has tiny invisible "pushers" inside. These pushers line up in a certain way and never stop pushing. That’s what makes the brick act like a magnet. This kind of brick is like a permanent magnet.
How They Work
When you make a regular magnet, you usually use another magnet to help it get its "pusher" power. But a permanent magnet already has this power inside it, it doesn’t need any help from other magnets to stay strong.
Why They’re Cool
You can find permanent magnets in all sorts of places. Like your fridge door, the kind that holds up pictures and notes without you needing to use tape or pins! Or in your phone, helping it feel the motion when you swipe or tilt it.
They're like little helpers that never get tired, always ready to push and pull things around them.
Examples
- A compass needle pointing north no matter how many times you move it
- A toy car that keeps moving without needing a battery
