On the Five Properties of Magnet
First, the diaMagnetic
AntiMagnetic is a kind of material, when in the external Magnetic field, will be on the Magnetic field of the weak repulsion of a Magnetic scene.
Second, superconductors
Superconducting material, also known as superconductor (superconductor). When the Magnet of a conductor in a temperature, the resistance can be zero and said. Zero resistance and resistance to Magnetism are two main characteristics of superconductors. So that the superconductor resistance is zero temperature, called superconducting critical temperature. Neodymium Magnet: neodymium Magnet (Neodymium Magnet), also known as NdFeB Magnet, the chemical formula for the Nd2Fe14B, is a permanent permanent Magnet, so far has the strongest Magnetic permanent Magnet. Neodymium Magnet is Sumitomo special metal company Sagawa real people and others created in 1982, by its chemical formula can be seen mainly by the neodymium, iron and boron and other chemical elements formed. Neodymium Magnet with strong Magnetic properties are widely used in electronic products such as hard drives, mobile phones, headphones and so on.
Third, ferroMagnetism
FerroMagnetism refers to the Magnetic condition of a material with spontaneous Magnetization. The most widely known information in the iron, hence the name of the. Some of the data in the external Magnetic field under the effect of Magnetization, even if the external Magnetic field disappears, still able to adhere to its Magnetization of the situation and has the Magnetic, the so-called spontaneous Magnetization scene. All permanent Magnet have ferroMagnetic or ferriMagnetic. Basically, the concept of ferroMagnetism includes any material that exhibits Magnetic properties when there is no external Magnetic field. So far there are still people who use this concept. However, after a better understanding of the Magnetic material and its Magnetism, the experts made a more accurate definition of the concept. The Magnetic ions in the nucleus of a substance are referred to as ferroMagnetic when they point to its Magnetic direction. If only some of the ion Magnetic field to its Magnetic direction, known as the ferriMagnetic. If the direction of the Magnetic ions just offset each other (although all the Magnetic ions only point to the two opposite directions) is called antiferroMagnetic. The Magnetic scene of matter has a critical temperature at which it will occur. With respect to ferroMagnetic and ferrous Magnetic materials, this temperature is called Curie temperature; for antiferroMagnetic materials, this temperature is called Neil temperature. Some people think that the Magnet and ferroMagnetic material between the recruitment effect is the earliest known to the Magnetic.
Fourth, electroMagnetic properties
ElectroMagnet is able to pass the current to the Magnetic force of the device, in the electricity popular society is an indispensable thing, is a non-permanent Magnet, with the permanent Magnet with a Magnet. Superconducting electroMagnet: Superconducting Magnet is made of superconducting material made of superconducting coil of artificial Magnet.
Five, paraMagnetic
ParaMagnetism refers to the Magnetic condition of a data. Some data can be affected by the external Magnetic field, the occurrence of the opposite direction of the Magnetization vector characteristics. Such a substance has a positive Magnetic susceptibility. Contrast with paraMagnetic is known as antirust.
        All matter is composed of molecules, molecules from the Magnet plant atoms. The atoms are made up of nuclei and electrons, and electrons are constantly spinning, turning around the nucleus, and the two transitions of electrons will occur. However, they are not the same direction of movement, disorderly placed, so the Magnetic effect of the material offset each other, under normal circumstances without Magnetic display.
     In the external force Magnetic field, iron, nickel, cobalt ferroMagnetic material inside the electronic, electronic operation of the regular, the Magnetic effect, and the direction of the external Magnetic field consistent, then the occurrence of Magnetic. But such as copper, aluminum, lead, etc. These are not ferroMagnetic material guess the electrons, with how to strengthen the Magnetic field, the electronic display disorder, there is no Magnetic. Magnet can absorb iron nails, is due to the Magnetic field of the Magnet so that the nail Magnetization, the attraction between each other, nails firmly firmly with the Magnet.
        However, when the temperature of the Magnet increases, their internal molecular thermal movement is faster and faster. So, the increasing number of electrons does not have the order to move up. When the temperature increases to the extreme value, the intense molecular thermal motion, it will completely damage the direction of electronic movement, Magnetic also disappeared. The metal scientist calls the temperature at which the Magnet can be completely retreated as the Curie temperature.
        So, why the burning of the Magnet is not strong enough to suck the nail on the truth here can be solved. As the burning more red, to clarify the higher the temperature of the Magnet, the general has exceeded 800 ℃. Conversely, if the temperature is reduced, if the Magnet is Magnetized from the beginning, it is still the same with Magnetic. Such as kitchen appliances ------ rice cooker that is the use of such a principle to make.
