Why do the same poles attract each other and the opposite poles repel in the electric field magneti

Conceptual magnets: Generally defined as objects capable of attracting substances such as iron, cobalt, and nickel.

Magnets are generally divided into permanent magnets and soft magnets.

Permanent magnet: that is, a magnet that can maintain its magnetism for a long time, permanent magnet is a hard magnet, not easy to lose magnetism, and not easy to be magnetized.

Soft magnets: As the materials of conductive magnets and electromagnets, the polarity of soft magnets changes with the polarity of the applied magnetic field.

properties and functional properties.

The magnet has bipolarity, the magnetic north pole N, the magnetic south pole S, and the two poles N and S poles are still cut off. A single pole cannot be present. At the same time, the magnet has directionality, if you hang a magnet, you will find that its south pole points to the geographic south pole and the north pole points to the geographic north pole.

There is an interaction between the acting poles, with the same name repelling the poles and the different names attracting the poles. There is a substance around the magnet that causes the needle to deflect, and this substance is called a magnetic field in physics. The distribution of the magnetic field is usually represented by magnetic inductance lines.

That's probably all junior high school students are required to know.

Reason: The magnet is divided into two poles, the N pole and the S pole, from the S pole to the N pole inside the magnet and from the N pole to the S pole on the outside. The same poles repel each other, and the opposite poles attract each other. The forces that attract or repel each other are magnetic field forces and are produced in a magnetic field.

The midpoint of the bar magnet is hung with a thin wire, and when it is stationary, its two ends point to the south and north of the earth, the one end pointing north is called the north pole or n pole, and the one end pointing south is the guide pole or s pole.

It's actually quite simple: 2 poles, one of which generates a magnetic field, and the other is seen as an energized coil (the magnetism of a magnet is formed by molecular currents), just like an electric motor. This is where amperage comes in.

f=bilb, the magnetic induction field at the location of the coil; i, the current passing through the wire; l, the length of the energized wire.

Then it is necessary to determine whether it is attracted or repulsed. High school physics is solvable. Deeper, you need to learn the magnetism of the material.

1. The poles of the same name repel each other, and the poles of different names attract each other. This is the law of interaction between magnetic poles.

As for why such a law exists, it must be related to the microscopic structure of the material world. All you need to know now is this law, and prepare yourself mentally and intellectually for the future to delve into the inner mystery of this law.

2. The interaction between magnets is realized by magnetic fields.

Since a magnetic field is generated around the magnet, the co-directional magnetic fields repel each other and the counter-magnetic fields attract each other.

In other words, when two magnetic poles are close to each other, the magnetic fields that "touch" each other will repel each other in the same direction and attract each other in the opposite direction. Since there is no chance of intersecting between the magnetic field lines, the magnetic fields that are opposite to each other will be "spliced" due to mutual attraction, and the magnetic fields after "splicing" will bulge due to the repulsion of the magnetic fields in the same direction. This also formed the magnetic inductance lines in our experiment.

You can draw the magnetic field lines of the poles:

When the same poles are placed together, the arrows of their magnetic inductance lines are facing each other, because the magnetic inductance lines cannot intersect, so they have to avoid each other, so they repel each other.

When the opposite poles are put together, their magnetic inductance lines will be in the same direction, and then the two magnetic inductance lines will merge into one (if they do not coincide, then at infinity, the two will intersect, contrary to the principle), so they attract.

Right. The basic property of a magnetic field is the action that produces a force on the magnet placed in it.

Therefore, the interaction between the magnetic poles is also done by the magnetic field.

Magnetic field: The magnetic field is a special substance that cannot be seen or touched, the magnetic field is not composed of atoms or molecules, but the magnetic field exists objectively. The magnetic field has the radiative properties of wave particles.

There is a magnetic field around the magnet, and the interaction between the magnets is mediated by the magnetic field, so the two magnets can act without contact. An electric current, a moving charge, a magnet, or a special form of matter that exists in the space around the changing electric field. Since the magnetism of a magnet is the same as the current, the current is the movement of an electric charge, so in a nutshell, the magnetic field is generated by the change of the moving charge or electric field.

From the point of view of modern physics, the only ultimate components that can form charges in matter are electrons (with a unit negative charge) and protons (with a unit positive charge) [1], so the negative charge is a point object with excess electrons, and the positive charge is a point object with excess protons. The real source of the field where the moving charge produces the magnetic field is the magnetic field produced by the moving electrons or moving protons. For example, the magnetic field generated by an electric current is the magnetic field generated by electrons moving in a wire[2].

The poles of the same name attract each other, and the poles of the same name repel each other.

The simpler the problem, the more complex the explanation, and the explanation often requires more advanced knowledge, and much of the current knowledge about magnetic fields is only hypothetical. Because the current observation methods cannot see the subatomic structure, let alone the structure of the magneton, here can only give you a vague and inadequate explanation, the magnetic field is generated by the molecular current, when the homogeneity of the magnet is close, the molecular current has a tendency to weaken, so a repulsive electromagnetic force is generated.

Two polar magnets attract each other, of course, because of the magnetic field.

The essence of the magnet is such that first of all, the cause of the molecular pole is that there are ring-moving electrons in the molecules inside the magnet. While the electrons move in a ring, the electrons also rotate. The rotating electrons hit the surrounding chaotic photons, causing the chaotic photons to shoot from one side of the electron's ring-like motion to the other.

If the side that enters the chaotic photon is called the n-pole, the side that emits the photon is called the s-pole. That is, the circulation of electricity forms electron magnets, which produce the smallest magnetic field. When the S pole of a magnet is close to the S pole, both sides emit photons, and the photons collide with each other, increasing the pressure in the contact area, so that the two poles repel each other.

When the n pole meets the n pole, both poles inhale the light and shoot the branches, so that the surrounding photons flow inward and collide with each other to produce high pressure, so that the two poles leave and repel each other. When the n pole meets the S pole or the S pole meets the n pole, they are always one emitting photon and the other absorbing the photon, creating a flow of photons that reduces the pressure and brings the poles closer to each other, i.e., attracted. This is the microscopic mechanism of magnetism.

In ordinary matter, the molecular arrangement is disordered, and the magnetic field of electrons in one molecule or atom cancels each other out with the other, so there is no magnetism overall. The molecular atoms in the magnetic and bright iron are arranged in an orderly manner, the direction of the magnetic poles is the same, and the magnetic field strengthens each other, so that the magnet has strong magnetism.

Physics never studies the essence.
