Episode 12 Creating a Monopole

You have probably seen the diagram of magnetic field lines of a magnet, where a magnetic field line comes out from the N-pole and goes into the S-pole... 

I'm sure you've seen the diagram of magnetic field lines of a magnet. You may have learned that different poles attract each other and the same poles repel each other in science experiments at school.

We intuitively understand that N poles (the side where the magnetic field lines exit) repel each other, but it is difficult to understand why S poles (the side where the magnetic field lines enter) repel each other.

Rather, I think they are pulling each other because they are sucking each other in, resulting in negative pressure.

In fact, has anyone investigated in the past whether the repulsion between N poles and the repulsion between S poles of the same magnet are slightly different?

But the repulsion between the S poles is clear from the actual experiment. There seems to be some secret here that we haven't recognized yet. I thought that the magnetic field lines are not coming in and out in a simple straight line, but rather in a spiral.

The magnetic field lines extend from the N-pole in a right-handed spiral, and the same N-pole on the other side extends in a right-handed spiral.If they collide in the middle of the spiral, the direction of rotation will not mesh and they will repel each other because they are facing each other clockwise.

In the case of S-pole pairs (the magnetic field lines are facing each other in a leftward spiral when viewed from the S-pole side), the magnetic field lines try to capture the leftward spiral, but again, the directions of rotation do not mesh. I think there is a stronger repulsive force than a simple straight magnetic field line.

This is the quantum that is predicted to exist in the Grand Unified Theory. Magnets usually have N and S poles that exist together and cannot be separated. A monopole, as the name suggests, is a quantum that exists alone, with only the N and S poles.

Is it possible to create this monopole instead of discovering it?

...... I think it is possible to create a monopole by combining positive and antimatter. Putting aside the idea of annihilation for a moment, please listen to what I have to say.In another topic, I mentioned that magnetic force is transmitted through space in the form of a spiral. In fact, the direction of rotation of the spiral is different between positive and antimatter, even though they have the same N-pole, for example.

This means that the N-pole of positive matter and the N-pole of antimatter do not repel each other, but attract each other.

In other words, if you bring the N poles of a positive and an antimatter magnet close together, you get a monopole, which is a magnet where both poles are S poles.However, it depends on whether you can keep them from annihilating each other.
