Will Strong magnets demagnetization?

- Nov 10, 2017 -

    Powerful magnets have special forces that, like electricity, can not be seen or felt by humans, but their influence is ubiquitous. The magnet can be easily made to fit the entire job. We all know that there is a gravitational field between things. The same magnetic field, with a field filled with poles around the space. The idea is to represent the magnetic field of a magnetic field of the size of the number of lines. The closer the magnetic line is, the stronger the magnetic field is, and the weaker the magnetic line is, the weaker it is. Strong magnets in the movement of charged particles will be subjected to a magnetic field called Lorentz force effect. Due to charged particles in a different magnetic field suffered by the strength of the Lorentz magnet to distinguish between the strength of the uneven magnetic field. Tesla is an international unit dedicated to measuring flux density. The magnetic flux density is the basic physical description of its magnetic field, and magnetic field strength is the amount of secondary magnetic field. Strong magnet claims permanent magnet, then, it really will not demagnetize it?

     Logically speaking, a strong magnet demagnetization has two elements, temperature and oxidation, the temperature is too high beyond the Curie temperature of 300 degrees Celsius will be lost. If the maintenance is bad oxidation will be lost magnetism, and this is the biggest reason for the failure of the use of the magnet. Strong magnet with small size, light weight and magnetic characteristics, so far the best price-performance magnets. Magnet, as the third generation rare earth permanent magnet material, has a high function price ratio. It is widely used in the industries of power, transportation, machinery, medical treatment, IT and home appliances. Especially with the development of knowledge economy represented by information technology, To rare earth permanent magnet industry and other functional materials continue to bring new uses, which brings more extensive NdFeB industry market prospects.
