What are the North and the South Pole of a magnet?

The north pole and the south pole of a magnet are the essential elements to form a magnetic field with a respective force. It can influence the material, shape or coating.

What are the North  and the South Pole of a magnet?

A permanent magnet has two different magnetic poles, called the north and south poles.

The magnetic field has its origin in the North Pole. The magnetic field extends from the north pole to the south. The course can be visualized through field lines. The field lines are inside the magnet. Magnetic poles of the same charge repel each other. Thus, the north pole with another north, the south pole and with another south pole are repelled.

On the other hand, the mutual poles attract each other. This is how the north and south poles dress. It is a characteristic property of magnets that each magnet has two poles. That is the difference between electric fields and magnetic fields.

Influence of magnetic poles on a magnet

When the current flows, a magnetic field is created and the electric charges move. In the case of magnetic fields always arise with two poles. Due to the two poles, this field is also called a dipole field. It must be compared with an electric field created by two opposite charges, also called electric dipole.

 

The magnetized material is called a permanent magnet. Permanent magnets can also be regarded as elementary magnets. The sum of the elemental magnets gives the magnetic field of a permanent magnet. Atomic circular currents have the same effect as electronic spins. They also have a magnetic north and south pole.

north and south pole 

For example, an electric charge consists of a negatively charged electron and causes an electric field. To produce a single magnetic pole, it is not possible with a single magnetic charge.

When talking about electric field sources, it actually refers to electric charges. The magnetic field is said to be free of waves. When the electric charges move, a dipole field with north and south poles starts. The freedom of the source of a magnetic field has not been demonstrated to date, but no one has seen a magnetic charge.

 

Mathematically, however, it can be proved with Maxwell's equations that the appearance of individual magnetic poles is impossible. Since the Maxwell equations could not be proven to date, we must pass their own law.

If you approach the north pole from one bar magnet to another magnet, they repel each other. But if you approach the south pole of a bar magnet, the north pole of another magnet, the two magnets attract each other.

The forces emanating from one magnet show the magnetic field. This is indicated by magnetic flux density B.

 

Examples of magnetic poles in objects

The earth has a magnetic field, which is caused by currents from inside the liquid earth. The point of penetration of the theoretical axis of rotation of the world through the earth's surface in the direction of the polar star is called the earth's north pole. Sometimes this point is also a little more precise than that of the geographic North Pole. The Earth's magnetic south pole is near the geographic North Pole, so the compass' north pole is north of the magnetic south pole.

Another example is neodymium magnets, also known as super magnets. Neodymium magnets are among the strongest in the world. The magnets consist of an alloy of neodymium, boron and iron (NdFeB). The use is very diverse.
