Existance of three poles of magnet

In summary, two magnets with the same pole strength and length were discussed. It was mentioned that when brought together forcefully and stuck with glue, the combination does not create a magnet with three poles, but instead has four poles - one at each end and two near the join. It was also noted that the poles of a magnet are not at the ends, but some distance inside the metal. The net magnetic flux through a closed surface around this setup would be zero, as di-poles are always present when dealing with magnetism.

I consider two magnets of smae pole strength and length.
If i bring either of similar poles of the magnet forcefully near and stick with a glue.

Is the combination a magnet with three poles?

Thank you for your help

The net magnetic flux through a closed surface around this setup would haft to zero .
I'm pretty sure when dealing with magnetism we always have di-poles.

Sadly no.

The poles of a magnet are not at the ends. They are some distance inside the metal.

If you stick the magnets together you still have four poles - one at each end and two close together near the join.
 

1. What are the three poles of a magnet?

The three poles of a magnet refer to the North pole, South pole, and Neutral pole. The North and South poles are the traditional poles that we are familiar with, while the Neutral pole is the point in between the North and South poles where the magnetic field is at its weakest.

2. Are there any scientific theories that explain the existence of three poles of a magnet?

Yes, there are several theories that explain the existence of three poles of a magnet. One theory is the dipolar model, which suggests that every magnet has both a North and South pole. Another theory is the monopole model, which suggests that magnets only have one pole, but the interaction between multiple magnets creates the illusion of three poles.

3. How do the three poles of a magnet affect its magnetic field?

The three poles of a magnet affect the strength and direction of the magnetic field. The North and South poles have a stronger magnetic field, while the Neutral pole has a weaker magnetic field. The direction of the magnetic field is from the North pole to the South pole.

4. Can the three poles of a magnet be separated?

No, the three poles of a magnet cannot be separated. The poles are a fundamental property of a magnet and cannot exist independently. If a magnet is broken into smaller pieces, each piece will still have all three poles.

5. Are there any practical applications of the three poles of a magnet?

Yes, the three poles of a magnet have various practical applications. For example, in MRI machines, the magnetic field produced by the North and South poles is used to create images of the body. The Neutral pole is also important in magnetic levitation technology, where the balance between the North and South poles is crucial for objects to float in mid-air.
