Description
Technical field
This utility model is related to a kind of body formed magnetizer of permanent magnetism, it is particularly a kind of being capable of direct measurement to forming magnetic field
The magnet forming magnetic field monitoring magnetizer of monitoring.
Background technology
From the point of view of the developing history of permanent magnet material, the carbon steel that late nineteenth century uses, magnetic energy product (BH) max (weighs permanent magnetism
Body stores the physical quantity of magnetic energy density) not enough 1MGOe (million is high difficult to understand), and the external Nd-Fe-B permanent magnet materials produced in batches, magnetic energy
Product has reached more than 50MGOe.Since this century, the remanent magnetism Br of material improves very little, and the raising of energy product will give the credit to coercivity
The raising of Hc.And coercitive raising, mainly have benefited from the understanding to its essence and the discovery of high magnetocrystalline anisotropy compound,
And the progress of technology of preparing.
Earlier 1900s, people mainly make permanent magnet material using carbon steel, wolfram steel, chromium steel and cobalt steels.Twentieth century 30 years
Dai Mo, AlNiCo permanent magnet material is succeeded in developing, and the large-scale application for just making permanent magnet material is possibly realized.The fifties, barium ferrum oxygen
The appearance of body, had both reduced permanent magnet cost, and the range of application of permanent magnet material is widened into high frequency field.To the sixties,
The appearance of rare-earth cobalt permanent magnet, the then application for permanent magnet opens a New Times.
1967, Strnat of Dayton universities of the U.S. etc. successfully made SmCo5 permanent magnets with powder bonding method, mark
Will the arrival in rare earth permanent magnet epoch.So far, rare earth permanent magnet has experienced first generation SmCo5, second filial generation precipitation hardenable
Sm2Co17, develops into third generation Nd-Fe-B permanent magnet materials.
Additionally, being used as also Cu-Ni-Fe, Fe-Co-Mo, Fe-Co-V, MnBi, A1MnC of permanent magnet material in history
Alloy etc..These alloys are seldom adopted because performance is not high, cost is not low in most of occasions.And AlNiCo, FeCrCo,
The alloys such as PtCo are also applied in some special occasions.At present Ba, Sr ferrite remains the maximum permanent magnet material of consumption, but
Its many application is gradually by the replacement of Nd-Fe-B classes material.Also, the output value of current rare-earth permanent magnetic material substantially exceeds
Ferrite permanent-magnet materials, the production of rare earth permanent-magnetic material has evolved into a big industry.
Permanent magnet applications scope is varied, including television set, speaker, and Music centre loudspeaker, radio, Briefcase buckle,
Data wire magnet ring, computer hard disc, cell phone vibrator etc..This kind of permanent magnet of speaker is to use the power on coil to move in magnetic field
Principle carry out sounding.Permanent magnet on loudspeaker is then the magnetic field that electric current the is produced phase therewith using when electric current changes in coil
Effect so that coil and Magnet relative position change, drives the cone on loudspeaker to vibrate, and promotes air and propagates this
Individual vibration, human ear is so as to hearing sound.In a word, permanent magnet is omnipresent in people's life, and it facilitates our production life
It is living.
Permanent magnet can be classified as follows：By material point, the first big class is:Alloy permanent magnet material, including rare earth permanent magnet
Material (neodymium iron boron Nd2Fe14B), SmCo (SmCo), aluminum nickel cobalt (AlNiCo)；Second big class is:Ferrite permanent-magnet materials
(Ferrite)。
It is divided into by production technology difference:Ferrite sintered body, bonded ferrite, injecting ferrite, these three technological basis magnetic
Brilliant orientation is different side's property and the anisotropy magnet such as to be respectively divided into again.These are exactly main permanent magnet material on the market, more also
Because production technology is former or cost reason, it is impossible to widespread adoption and eliminate, such as Cu-Ni-Fe (cupro-nickel ferrum), Fe-Co-Mo (ferrum cobalts
Molybdenum), Fe-Co-V (ferrum cobalt vanadium), MnBi (manganese bismuth).
Artificial permanent magnet, is required for being magnetized in its forming process, so that magnet has magnetic, and the magnetic that magnetizes
Size can directly influence magnetization quality, and consider device mask effect and leakage field factor in the prior art, all without
Method carries out effectively intuitively monitoring to magnetic field of magnetizing, and affects the efficiency that magnetizes.
