Okay kiddo, so you know that everything in the universe is made up of tiny little things called atoms, right? Well, scientists have figured out a lot about how these atoms work and how they interact with each other. One of the most famous scientists who studied atoms was a man named Werner Heisenberg.
Heisenberg discovered something really important about atoms that he called the "Heisenberg Uncertainty Principle". This means that you can't know everything about an atom all at once. You can either know where it is or how fast it's moving, but you can't know both perfectly.
This idea helped scientists understand how magnets work and how they interact with each other. They came up with something called the "classical Heisenberg model" to explain this.
Imagine you have a bunch of magnets, like a bunch of little toys with magnets inside them. When you put them all together, they can either all be pointing in the same direction or they can be pointing in different directions.
In the classical Heisenberg model, scientists look at how these magnets interact with each other. They use math to figure out the energy of the magnets and how they will move around.
There are different versions of the Heisenberg model, but they all help scientists understand how magnets work and how they behave in different conditions. Cool, huh?
