So That The NdFeB Segment Of The Most Simple Way To Lose Magnetic

So that the NdFeB Segment of the most simple way to lose magnetic
        All matter is composed of molecules, molecules from the NdFeB 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 placement, the magnetic effect, and the direction of the external magnetic field, then the magnetic will occur. 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. NdFeB Segment can absorb iron nails, is due to the magnetic field of NdFeB Segment of the magnetic nail magnetization, the attraction between each other, nails firmly with the NdFeB Segment together.
        However, when the temperature of the NdFeB Segment increases, their internal molecular thermal motion becomes 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. Metal scientists to the NdFeB Segment can be completely deviated from the magnetic temperature known as Curie temperature.
NdFeB Segment with magnetic force is determined by the characteristics of the NdFeB Segment if the atomic current is explained that the current is generated by the magnetic field magnetization of other objects magnetized objects generated electric field effect of each other effect.
Most of the material is composed of molecules, molecules are composed of atoms, atomic NdFeB plant is by the nucleus and electrons. Inside the atom, the electrons are spinning and rotating around the nucleus. Both of these movements of electrons occur magnetically. But in most substances, the direction of electronic movement is different, mess, the magnetic effect offset each other. Therefore, most of the material under normal circumstances, does not appear magnetic, no external magnetic force.
Iron, cobalt, nickel or ferrite and other ferromagnetic materials are different, it is within the electronic spin can be consciously placed in a small range, constitute a conscious magnetization area, this self-conscious magnetization area called magnetic Domain. Ferromagnetic material magnetization, the internal magnetic field neatly arranged in the same direction, so that the magnetic reinforcement, it constitutes a section of NdFeB. NdFeB Segment of the iron absorption process is the iron block of the magnetization process, the magnetized iron and NdFeB Segment is not the same as the polarity of the attraction, iron and nylon neon layer firmly with the "sticky" Together. We said that the Nd-Fe-band section of magnetic, NdFeB Segment with magnetic force.
For all magnetic materials, it is not at any temperature with magnetic properties. Typically, the magnetic material has a critical temperature Tc above which the arrangement of the atomic magnetic moments is disordered because of the intense thermal motion of the atoms at high temperatures. At this temperature below, atomic magnetic moment placed regular, spontaneous magnetization occurs, the object becomes ferromagnetic.
Using this feature, we developed a lot of control components. For example, we use the rice cooker on the use of the magnetic material Curie point characteristics. In the bottom of the rice cooker installed a piece of NdFeB Segment and a Curie point of 105 degrees of magnetic materials. When the pot of water dry in the future, the temperature of the food will rise from 100 degrees. When the temperature reaches about 105 degrees, because the NdFeB Segment of the magnetic material occupied by the magnetism is not seen, NdFeB Segment on it lost its suction, then NdFeB and magnetic materials between the tension spring will be Separate them, together with the stock power switch is turned off, stop heating.
        Therefore, the burning red neodymium iron boron section why the suction is not strong nails on the truth here can be solved. As the burning more red, clear neodymium iron boron section of the higher temperature, generally exceeded 800 ℃. On the contrary, the temperature decreases, if from the head to the NdFeB Segment magnetization, it is still the same with the magnetic. Such as kitchen appliances ------ rice cooker that is the use of such a principle to make.
