Kev tshawb xyuas tag nrho ntawm lub ntsiab lus ntawm cov qauv vibrating coagetometer (vsm)

A Vibrating Qauv Magnetometer (vsm)yog lub cuab yeej siv tau haib siv los ntsuas covCov Khoom Sib Nqusntawm cov ntaub ntawv. Nws yog ib qho siv tau nyob thoob plaws ntawm cov khoom sib nqus, suav nrog:

• Ferromagnetic
• Ferrimagnetic
• Antiferromagnetic
• Ua tsis tau
• Diamismntaub ntawv

Vsm ua lub luag haujlwm tseem ceeb hauv kev sib nqus ntawm cov hlau nqus, cov khoom siv hluav taws xob, sib nqus, cov khoom sib nqus, thiab cov khoom siv roj ntsha li cov proteination.

Nrog VSM, intrinsic sib nqus cov khoom xws li:

• Salmation magnetization (ms lossis σS)
• Curie Kub (TC)
• Kev sib xyaw ua ke (HC)
• Remanent Magnetization (Mr.

tuaj yeem raug kuaj pom tseeb. Tom qab kwv yees tusdemagnetization yog factor (n)Nyob rau hauv cov qauv ntsuas ntsuas kev ntsuas, cov sib nqus ntxiv xws li:

• Kev tsim txom induction (BS)
• Ua kom haum cov teb (BHC)
• Cov khoom lag luam hluav taws xob ((BH) Max)

tseem tuaj yeem suav. Ntxiv mus, los ntawm kev txheeb xyuas lubHysteresis Voj, qhov kev coj sib nqus tag nrho ntawm cov qauv tuaj yeem raug ntsuas.

Lub cim vibrating magnetometer feem ntau muaj peb lub ntsiab hluav taws xob:

• Electromagnet System- Tsim kom muaj kev tsis zoo sib nqus.
• Qauv Mus Rau Cev Txheej Txheem- yuam cov qauv los ntsuas kom tshee hnyo.
• Kev Tawm Tsam Kev Tawm Tsam Kev Ntsuas- Kev ntsuas qhov ua rau muaj hluav taws xob voltage tsim los ntawm cov qauv vibrating sib nqus.

Lub hauv paus ntsiab lus ntawm VSM yog raws liFaraday Txoj Cai ntawm Electromagnetic InductionThiab tusKev co ntawm cov qauv hlauetizednyob rau hauv lub teb sib nqus. Ntawm no yog li cas nws ua haujlwm:

Kev co pib:
Tus osCillator cov khoom siv ib qho Sinusoidal tam sim no rau tsav kauj ntawm lub taub hau co. Qhov no ua rau cov pas nrig cuv-thiab cov qauv mounted ntawm nws-kom tshee hnyo (ω), feem ntau yog ob peb kaum ntawm HZ.

Sib nqus lus:
Raws li cov qauv vibrates nyob rau hauv lub pob sib nqus tiaj (h), nws tsim ALub Sij Hawm-sib txawv sib nqus Dipole tebCov. Daim teb no tsim ancesHloov kev voltageNyob rau hauv lub chaw ruaj ruaj nrhiav cov coils muab tso rau nyob ze.

Kev Tshawb Nrhiav Cov Ncauj, Amplification:
Cov cim taw qhia, muaj tib qho zaus (ω) raws li lub teeb liab siv los ntawm oscillator, yog pub rau hauv aTheem-Xauv AmplifierCov. Qhov no amplifier tsuas yog cov txheej txheem teeb tsa sib txuam cov zaus thiab theem ntawm cov ntaub ntawv, li lim tawm suab nrov thiab tsis muaj kev cuam tshuam.

Cov Tso Tawm Voltage:

A DC cov zis voltage (vₘ)yog generated, uas yogmuaj feem proportion rau tag nrho lub sijhawm sib tuavntawm cov qauv.

Qhov thib ob tawm cov zis hluav taws xob (vₕ), ib feem ntawm kev thov cov teb magnetic (h), tseem raug ntsuas.

Cov ntaub ntawv tsom xam:
Los ntawm plotting vₘ tiv velius vₕ, aMagnetization Nkhaus lossis Hysteresis Vojyog tau. Daim duab no muab cov tswv yim tseem ceeb rau hauv tus qauv sib nqus, xws li nws teb rau lwm thaj teb thiab khaws cia li cas khaws cia hlau nplaum.

VSM yog qhov ntsuas ntau yam thiab cov cuab yeej zoo rau kev tshawb xyuas cov yam ntxwv sib nqus ntawm ntau cov ntaub ntawv. Nws lub peev xwm los ntsuas qhov tseem ceeb xws li cov khoom siv sib xyaw ua ke, thiab kev sib nqus ntawm cov khoom siv science, physics, electronics, thiab biomedical kev tshawb fawb.

Qhia rau kuv paub yog tias koj xav tau qhov no tig mus rau hauv kev pom ntawm cov neeg pom kev lossis lub powerpoint-style txheej txheem rau kev nthuav qhia siv!
