O magnetism it is the capacity for attraction that one body exerts on another.
The magnets that have magnetism natural has in its. magnetic rock structure called iron oxide or magnetite.
Artificial magnets, on the other hand, are created from nickel-chromium, which are metallic alloys.

O magnetism is explained by this bipole force. Let's say a material is made up of different poles.
When these poles are placed in contact with each other. materials, the same poles tend to repel each other while the different poles attract. This is called a magnetic dipole.
Atoms are considered to be magnets having a north pole. and south. An example of magnetism are the so-called compasses.
The compass is a magnet and so is our planet earth. AND. no matter where you're holding a compass, it will always point. to the north pole.
This is the result of the earth's magnetic pole that. will always indicate the pointer in this direction. This earth pole works like. a reference for compass alignment.
Since the seventh century such concepts existed. Some. texts made by Greek scholars who already knew of the existence of magnetism. And also of bodies well present in a region with the name of Magnesia.
And that's where the name of the properties came from. attraction and repulsion of some existing bodies. Who investigated this was the. mathematician, philosopher and physicist Thales of Miletus.
It was he who studied the attraction of lodestone, the magnet. natural, along with iron.
The compass was already used by Chinese navigators. in the seventh century and it is believed that they in addition to using the instrument as a compass, also had it with an amulet.
In the 13th century, Pierre Pelerin de Maricourt who. described the specific properties of the compass. And then, William. Gilbert determined after studies that our planet was magnetic.
Cause the compasses always point north.
Magnetic field interaction can be done a. distance without the need for body contact. Just like energy is. related to a system, the magnetism has its field.
This magnetic field interacts with substances with. electric and magnetic currents. To make the lines of a field apparent. magnetic, there is a specific technique.
Iron filings are spread on a paper where they rest. one or more magnets. Small pieces of iron filings are arranged on. curved lines connecting the north pole to the south pole.
This is called a field or force line.
The outer field of a magnet has field lines that. they leave at the north pole and enter at the south pole of this magnet.
The magnet, better known as a magnet, is a body. Magnetic rocks which are magnetic rocks or magnetized irons. He's a dipole, yes. two poles.
Are called positive and negative that has the power of. attract ferromagnetic bodies. Among them are the well-known lodestone, magnet. Natural.
Magnetization is the process where magnets are manufactured. In this process a neutral body receives magnetic property and attraction.
Some metal alloys and the important iron, if. they magnetize easily.
Artificial magnets are essential for manufacturing. of compasses, electric power generators and electronic devices.
the strength of magnetism is more intense than a. force of electrical energy.
Magnetic flux is a portion of the magnetic field in. its totality passing in a specific area.
It is important to have an understanding of the flow to know. how the object will behave in this area with magnetic force.
Magnetic poles cannot have separation. For more. if you break a magnet in half, it's going to have a north pole and a south pole. again.
It's a well-known exam. It is. machine creates magnetic fields by creating images of the patient's body.
This procedure is possible because hydrogen atoms in our body can emit radio frequency when stimulated by an external magnetic field.
