Magnetic pressure

Magnetic pressure is like a push or a force that magnets use to stay away from each other. Think of magnets like two kids on a playground who don't want to be too close to each other. They use their hands to push each other away so that they don't bump into each other. Magnets work the same way, but instead of hands, they use a force called magnetic pressure.

Magnetic pressure happens because magnets have a north pole and a south pole, and these poles have opposite charges. Just like how opposite ends of a battery attract each other, opposite poles of a magnet repel each other. This means that the north pole of one magnet will push away the north pole of another magnet, and the south pole of one magnet will push away the south pole of another magnet.

The magnetic pressure between two magnets depends on how strong the magnets are and how close they are to each other. The closer they are, the stronger the magnetic pressure will be. If the magnets are very strong and very close to each other, the magnetic pressure can even be strong enough to make the magnets fly apart!

Scientists use magnetic pressure for lots of things, like creating strong magnets for MRI machines that can see inside your body, or for making sure that spacecraft stay on course when they are flying through space. So remember, magnetic pressure is like a force that magnets use to stay away from each other, just like two kids on a playground pushing each other away.
