When I was a child, we are curious about magnet, a black thing can absorb iron, can even suck out a lot of iron powder from the dust, make them dance.
Magnets can be more than just a children's toy, however, due to the atomic structure is very special, can produce a magnetic field, scientists have used this feature to its application in various industries, including the IT industry.
But with the development of science and technology, the magnet in the notebook design is also more and more wonderful.
In a magnetic material, local magnetic moment can rotate in different directions and alignment.
At absolute zero, the local magnetic moment will be aligned to produce the strongest magnetic magnet.
As temperatures rise gradually, the magnet is becoming more and more weak, because more and more local magnetic moment will rotate left alignment lines, leads to increased temperature magnetic subset.
Magneton are similar in many aspects of electronic, they can be charged and thermal conductivity.
Electron will respond to the electric field and temperature gradient & ndash;
This phenomenon is called the thermoelectric effect.
The scientists investigated the magnet effect in recent years a variety of applications, such as thermoelectric generator, it can convert heat directly into electricity, or without any moving parts and cooling effect.
According to this equation is derived, liao, zhou and Chen magneton transmission are also described two new equations.
Using the new formula, they predict a new magneton cooling effect, similar to the thermoelectric cooling effect, namely magneton under magnetic field gradient will carry heat from the magnet small a magnet, incredibly can firmly stick to hundreds of grams of weight of the base, only components we also find many magnet was silver, this completely overturned our childhood to the magnet should be black, magnetic nor strong impression.
Why is that?
Actually, when I was a child often contact the magnet ferrite magnet, is a kind of iron oxide, its magnetic is quite limited.
Now the notebook is mostly used in ndfeb magnets such as synthesis, this kind of magnets in adding neodymium iron and boron rare material, so have a shiny metal surface character, and powerful magnet magnetic than ferrite magnet enhanced several times, magnetic force is 640 times their own weight.
